Microsoft Sharepoint error "Length cannot be less than zero. Parameter name: length"

 

Question

On my Sharepoint Data Source I am seeing the following error

"Error Message: Microsoft Graph API Error: InternalServerError -- Length cannot be less than zero. Parameter name: length"

Where is this error pointing to and how can I fix this?

 

Answer

This error is coming from Microsoft's side and Support is limited with what we can do. This error is typically filtered out after a few attempts from our server. 

Typically this error is indicating that a negative number is being passed to a sub-string which is not valid (i.e a value of -1 is being passed). In order to locate which value it is please contact Microsoft to have them resolve the parameter length and point you to which value is sending an incorrect value.
