Errors observed in the JumpCloud Function App

[JustineTheHacker]

Hi Team,

We've recently used the JumpCloud data connector available in this repository. Logs are now flowing in to Microsoft Sentinel. However, we're seeing 2 errors in the log stream. See below:

Error 1:

We've already updated the runtime and the powershell core version to ~4 and 7.4 respectively based on the recommendation from this link -- #11535

To Reproduce

1. Go to 'Log Streams' in the Function App and monitor for a few minutes for the errors to appear.

Expected behavior
I am expecting to not see any errors within the log streams and the functions

Screenshots

Additionally, is it possible to set the logging level of the function app triggers? We're getting high number of logs into the AppTraces table -- as I understand it, it's possible to edit the host.json file to add the a line to specify the logging level (https://learn.microsoft.com/en-us/azure/azure-functions/configure-monitoring?tabs=v2)

Hoping for your kind response, thank you!
