I have a workflow that is pulling large sets of data from several databases and doing some minor transformation. The data is then output to several sheets in one excel workbook to a location on a shared drive. I am using a Block Until Done tool prior to each output.
Output 1 is set to Overwrite File (Remove) and Outputs 2 and 3 are set to Create Sheet.
The workflow had worked seamlessly until today where I am getting the below error message.


Anyone familiar with this error and how I can resolve?
