Error Code: CE042 - Something went wrong opening the Lucid integration

Hello All, 

This error appears after adding Lucid as an assignment submission type in Canvas LMS. What can we do to fix this?
Please let me know if I can provide additional information to assist with this question.

Thanks!

HI ​@HannahMarie,

 

Thank you for posting in the Lucid Community! As a first step, would you mind enabling 3rd party cookies and then trying again? Please take a look at this article for information on how to do this. If this doesn't solve the problem, could you please try opening a private/incognito window and trying again? 

 

If the issue persists, can you please send the following information:

  • Could you confirm if the issue persists on an alternate browser?
  • Could you confirm if you are following the steps listed here?
  • 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).

 

This will help us investigate this further. Thanks!

Hello ​@aishakhan,

 

Thanks for your response, and the issue persists. Following the information you shared, here are the steps I took to troubleshoot so far:

  1. Enabled third-party cookies in Google Chrome browser - got the same error
  2. Opened an incognito window and created an entirely new assignment following the guide you shared - got a different error: CE014-02
  3. Switched to Firefox - did not get an error, but the Lucid app did not load and is displaying a red folder icon

Here is the Javascript as requested. I appreciate your help!

 

Thanks,

Hannah Marie

Hi ​@aishakhan,

FYI, I just removed the dates from my test course and now the error is no longer appearing. I will check the actual course within the term to see if the CE042 error is still appearing there. 

Thanks,

Hi ​@aishakhan,

We tested again and successfully created the Lucid assignment in Canvas. Would you please provide some information about how dates in Canvas affect Lucid?

Thank you!
