Page countif function with multiple pages

I am using the countif function: {{=COUNTIF(DESCENDANTS(page),CONTAINS(THIS."model", "xxx"))}} to count the objects on the current page according to the data field “model”. I’d like to put this in a table that has columns to count the objects on multiple pages. For example, one column for corporate, one for engineering, and one for manufacturing (page names). Is it possible to use the countif function to reference objects on another page in the same file?

Are the curl examples wrong in the documented endpoints?

 I have been checking the documentation for embedding files and it appears that I am supposed to be generating a temporary token that is to be used when embedding files. This is the page I am looking at: https://lucid.readme.io/reference/documentembedstokenThe example curl is:curl --request POST \ --url https://api.lucid.co/embeds/token \ --header 'accept: application/jwt' \ --header 'authorization: Bearer oauth2-...' \ --header 'content-type: application/json'This curl seems to be incorrect/missing data, as when I use the example I get the error The requested resource requires a valid Lucid-Api-Version header. So, I pass this header: Lucid-Api-Version: 1 in the curl (which I am assuming is correct but there is no good way for me to be sure) and I get the error Missing or invalid access token despite me passing in a valid access token. In addition, the documentation says I need to pass a body, including `origin`, and `embedId` (as optional) which is not included in the

Will there be newer data set API's coming?

I’d like to automate importing of CVS data but it appears the only API’s for that are in the legacy API which also requires OAuth 1.0? Is this correct and will there be newer API’s that are not legacy to meet this need?

BUG: https://api.lucid.co/documents/:id/trash

I’ve noticed that when I use the https://api.lucid.co/documents/:id/trash API call documented https://developer.lucid.co/rest-api/v1/#trash-document If I have the parent folder open in a browser window the document does not disappear. When I choose the Trash option from the Lucid web app ui the document vanishes. I have also noticed that when a document is created with a POST to https://api.lucid.co/documents the document shows up in the web app. If I click into the document that was deleted with the API trash call I get a notice the document is in the trash. Refreshing the browser page causes the trashed document to disappear. Also my first time trying to report a bug I’m not sure this is the best place so happy to have feedback on the correct way to report a bug.

Reference other existing libraries in an extension?

I love the Salesforce Well-Architected shape library and the Salesforce integration to connect and create ERDs but I don’t see an easy way to generate a document using the shape library from the ERD connector output.If I made a custom extension could that extension rely upon the Salesforce shape library or not? Or in general any other 3rd party shape library?

🎉 Exciting Updates from the Lucid Developer Platform! 🎉

Hello Lucid Developers! 👋We’re happy to announce some exciting updates to our Developer Platform, enhancing your experience and capabilities. Private PublishingUsers can now publish apps and integrations to share directly with their teams without needing approval by Lucid or having to post publicly on the Lucid marketplace.Privately-published apps will still be downloaded via the Lucid Marketplace but will only be discoverable by those who you have made the app available to through direct invitation. Otherwise, the app will be completely invisible to all other Lucid users.For a deep dive into how to get started with Private Publishing, check out our detailed guide in our Developer Documentation. Org Chart APIs We have just released our new Org Chart API endpoint. An org chart is a data-backed shape used to visualize organizational structures.The Org Chart API will allow you to create charts much more quickly by importing them from data rather than creating them manually. Technically,

No or very slow API replies from REST API

I am the developer of an application where we want to show pages from Lucidchart documents into our application. I want to show them by exporting each page as a jpeg file into our application. I created an OAuth 2.0 client and I can get and update a token without a problem. My application is written in PHP. To add the pages our users first search for Lucid chart documents. I use the Search document endpoint for that (https://api.lucid.co/documents/search). I then display the search results where the user can pick a Lucidchart document.Then, I use the Document Contents endpoint (https://api.lucid.co/documents/:id/contents) to retrieve what pages are in the document. I then loop over these pages to export each page to a jpg image with the Export Document endpoint (https://api.lucid.co/documents/:id?pageId=xxx).The problems I have, is that many times, the API simply doesn’t answer and times out. I almost never get an error message back from the API. I do sometimes I get a curl error 0 wit

Error when refreshing token

We are getting intermittent errors when refreshing Oauth2 tokens in our Rest API integration. We are using a legacy token (Admin > App Integration > General >App Integrations > Custom OAuth apps) and the app has been working in our test environment for months. We recently deployed to production and more users are using it more regularly. The same user will get a refresh token error one moment and then when they try again it errors (see below).We did have a scheduled process that was retrieving all documents from each user and therefore hitting the API more frequently (once per user every 15 minutes),  we have stopped that process  temporarily to see if that helps, but would like to know if there are any other known issues which would be causing the intermittent issues. {"type":"http.ClientResponse","code":400,"headers":{"Alt-Svc":"h3=\":443\"; ma=93600","alt-svc":"h3=\":443\"; ma=93600","connection":"close","Connection":"close","Content-Length":"166","content-length":"166",

Can I set document properties when importing a document?

I use the Import Document endpoint (POST https://api.lucid.co/documents) to create Lucidchart documents. I found no option to set document properties like the page size (I wanto to set that to A3) and the orientation (I want to set that to landscape).Is that even possible?

How to create a document with data in it based on a template?

Hi, I'm looking for a way to create a Lucidchart document based on a template and add my own data to it. I managed to create a document based on a template with the POST https://api.lucid.co/documents endpoint. I cannot add my own data however, as this doesn't seem to be supported by that endpoint.Another route could be to use the Import documents endpoint but then I cannot seem to specify the template to be used.Or am I missing something here?

FIELDLOOKUP and LOOKUP Formulas do NOT update after data updates

While using the FIELDLOOKUP and LOOKUP functions in my document I noticed that they did not update as the associated dataset was updated. Steps to reproduce: Create a new dataset with some minimal data Create a field (variable) on the page Use the FIELDLOOKUP or LOOKUP formula in the value of that field Verify the value matches the originally uploaded data Open the data panel and make a manual edit to the data in that dataset The value of the field does NOT change (it still reflects the value that was originally uploaded) - this seems to be a bug as it is not the expected/intuitive behavior From the data panel choose to Replace the dataset with a new set of values Verify the value of the field now reflects the newly replaced value in the dataset

This OAuth2 client is not available

My team developed a web application that uses a REST API to create and then embed the Lucid Chart documents into our website.We successfully tested the integration between our app and the Lucid. It works fine as long as the user is added to the collaborators in the developers panel.However, when other users test our application they get an error saying:“This OAuth2 client is not available”The account administrator installed our application package for the whole account, but the error still persists.We don’t use the Extension API and our application is totally external to the Lucid. We just need to use the REST API only.
