Azure Logic Apps is returning an Internal Server Error with the message: "The 'JavaScriptCode' action failed with error code 'UnknownError'." This issue has caused all logic apps to stop working simultaneously since yesterday. Additionally, even the placeholder code provided by Azure is failing as well.

Hi sf-8216,
The error you're seeing — The 'JavaScriptCode' action failed with error code 'UnknownError' likely points to a problem within the Logic Apps runtime when handling JavaScript actions.
What you can do:
Restart your Logic App and try again.
If the issue continues, try removing and re-adding the JavaScriptCode action.
To help you better understand, kindly refer to the documentation below:
For more details on these issue please refer below link as well.
I hope this addresses your query. Please let me know if you need any further assistance or clarification.
in the end the problem went away without any change from my side, so I assume this was a Microsoft bug
I tried creating a brand-new logic app and still faced the same issue

Same issue I am facing in one of my logic app for JavaScript inline code logic app step. This step was working fine from last 2.5 years and it's started failing intermittently from 16th April. On resubmission of same logic app failed run, logic app able to processed the failed record successfully. So if it's an issue with my JavaScript code or the data I am sending in the JavaScript inline step then it should be fail in retry as well but it's passing in retry every time. So sometime is wrong with the inline connector.
Hello sf-8216,
Thanks for the update. This seems to be issue with connector.
So, could you delete that connector and reconfigure the same.
Sometimes reconfigure will us help to resolve connector issues.
Please follow above suggested steps and let us know with an update.
Hello sf-8216,
Following up to see if you have chance to check my previous response and help with logic app status to proceed further.
in the end the problem went away without any change from my side, so I assume this was a Microsoft bug
