Error when inserting Lucid into a Canvas Assignment

Hi @Su-Hui C, 

Thank you for your reply! To add to @MayTse’s reply, can you provide some more details about the issue you are experiencing? This was a bug that should be resolved now, if you are still experiencing the issue, we want to make sure it gets resolved for you! What browser are you seeing the issue on? 

Hi all, have the issue in the attached image below is resolved as we still encounter it in our Canvas instance. Additionally, at the first time when I have integrated Lucid into Canvas LMS, I can access Lucid directly from course navigation but now it will redirect me to outside of Canvas. Could you please advise me why this happens? Thank you. 

Hi @Linhlee, 

This error has been reported to our development team. I apologize for any disruption this may cause, and I will update this thread with any new information. 

In the meantime, could you please try connecting your Lucid account via Canvas in a private or incognito window to help us narrow down the potential cause? Could you also try connecting to a different network or disconnecting from your VPN (if applicable)?

If those don’t resolve the problem, can you please send the following information so I can take a closer look?

• What is your role for this Canvas Course (i.e. Teacher, Admin, Faculty, or Student)?
• What Canvas environment are you using (Canvas Beta, Canvas Test, or Canvas Production)?
• Could you confirm if the issue persists on an alternate browser?
• Could you send a screenshot of the associated Javascript Console output? You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac).

Thanks in advance for your help and patience. Please follow along on this thread for updates, and post any additional questions or concerns below.

Hi ​@Ambar D  I will ask our teachers to do according to your advice and feedback to you soon. In the meantime, could you please advise that now we can’t access Lucid directly from course navigation on Canvas? As I see an explore Lucid button, when I click on it, it will navigate me to the new tab instead of being in Canvas. Thank you.

Hi ​@Linhlee, thank you for following up! Would you consider sharing a screen recording of your experience so we can take a closer look at the issue you are experiencing? 

Additionally, I wanted to share the following troubleshooting steps if you are still seeing the error code we discussed above. (Error Code: CE007) Please try the following steps:
1. Close your current browser tab.
2. Go back to your Canvas tab and refresh the page.
3. Reopen Lucid in Canvas and you should now be connected to Lucid.

Thank you for your help and patience as we work to resolve this! 

No, I mean when I access Lucid from course navigation on Canvas (see the attached screenshot) I click the explore lucid button → the system will navigate me to the different tab instead of staying inside Canvas. This is the expected behavior? As I remembered the first time when  I installed Lucid into my Canvas instance, I could access Lucid directly in Canvas after clicking the explore lucid button. But now it’s not, it will navigate me to the different tab. Please help to advise. Thank you. 

Hi ​@Linhlee,

My apologies for the misunderstanding. I’ve confirmed with our internal teams that what you are experiencing is the intended behavior - upon clicking ‘Explore Lucid’, the lucid.app website should open in a new tab. 

However, you can access Lucid directly within Canvas by embedding Lucid boards within assignments. For more information on that, I recommend checking out this Community post. 

I hope this information helps! Please let me know if you have any further questions. 

Hello Lucid Colleagues--I’ll join this thread to ask for help with a problem similar to what others have reported over the past months. We are building Lucidchart assignments in Canvas LMS for the first time, and on the instructor/designer side, everything looks good (e.g., embedding a Lucidchart template of our choice, so that every student opening the assignment will get their own copy). However, when I tested the assignment with a dummy student, the first-use steps brought the dummy student through the sign-up step but then to the same error page others have encountered. Here are the steps for the dummy student in screenshots:

Can you suggest some troubleshooting steps?

Thank you!

Hi ​@paulmorsink, 
Thank you for the reply! I am converting your post to a ticket so our support team can assist you!

I am running into the issue that these other people ran into months ago. Here is my error code I am a student trying to submit an assignment through the integrated tool I'm canvas. But when I hit "launch external tool" it I get this instead. I reached out to Canvas support who told me to reach out here.
