Sharpoint Output Error was working fine in December.

[BAvitia23]

Greetings, 

I have a workflow that is publishing to Sharepoint, that was working fine prior to the holiday season, this morning its resulting in this error. 

Did something change?

Error: SharePoint Output (33): WorkflowRuntimeError("Error while uploading file 'Alteryx Customer List.xlsx'.") has type WorkflowRuntimeError, but expected one of: bytes, unicode

Any ideas would be appreciated

Hi @BAvitia23 ,

this looks like the data type of a specific column has either changed in your workflow or on the actual list itself. 

If you are outputting to a list you need to map exactly what is on the list. For example, if you have a column which only allows a single character and you try to output a column with more than one it will error.

Check all your data types for each column are correct, the data within the columns is correct and all fields are mapped.

Hope this helps,

M.

I'm having the same problem.  I'm overwriting the Excel file, so matching existing fields is irrelevant.
