Confluence connector for lucid app is broken 
All embedded diagrams hang with “App is not responding. Wait or cancel?” 


Editing the macro settings returns :
 




Problem is typically resolved temporarily by uninstalling and re-installing the marketplace app but it only works for a few hours which is obviously untenable. 

I am admin on both Confluence and LucidChart

Hi ​@et-dgates, thanks for posting in the Lucid community! Could you open your browser's developer tools (Ctrl + Shift + J on Windows / Linux, OR Cmd + Opt + J on Mac), navigate to the Network tab:

?name=image.png

Then reproduce the issue, and see if there are any network requests that are failing as a result of this.

 

If so, in the headers section of the failed request, do you see an X-Lucid-Flow_Id? Could you send a screenshot of this, as well as the timezone and timestamp of the request? See example screenshot below:

Hi there 
Apologies i did not reply with the above - so the issue I found which I dont think is actually documented anywhere is when you set the connector up - everything works temporarily and then after around a day I experienced the issues 

Once the connector is INITIALLY setup there is an additional step where I believe you have to go into admin.atlassian.com > Connected Apps > LucidChart Diagrams Connector > Three Dots > Configure 

If I remember correctly you have to accept the connection in here - you might possibly need to accept on the Lucid side also

I hope this helps

I just get this screen of death whenever I try to do anything with the plugin.  I can’t uninstall it either.   I am an admin in confluence/jira/lucid.  I do see 403s in the HAR, and my flow id  

(call gives me a 400 Bad Request)

https://lucid.app/ac/confluence/admin?xdm_e=https%3A%2F%2Fhealnow.atlassian.net&xdm_c=channel-com.lucidchart.confluence.plugins.lucid-confluence__app-admin-lucidchart&cp=%2Fwiki&xdm_deprecated_addon_key_do_not_use=com.lucidchart.confluence.plugins.lucid-confluence&lic=none&userAccess=true&cv=1000.0.0-xxxxxxxxxxx

Of course you can’t uninstall it if you can’t get into the config.  So dead in the water.
