I have a workflow which seems to be problematic and when I run it I get
"an error occured during approval".
To see more detailed error logs I clicked on 'view wrokflow reports' in the workflow history section. But workflow reports itslef has a problem and I got this message:
"An unexpected error has occured. correlation id...". When I follow its correlation id in SharePoint logs I find these messages:
"failed to cache field with id ..."
"value doesn't fall within expected range"
How can I solve the problem of workflow reports itself? How can I see error log of my workflows?
