I have a huge problem. We created a Sharepoint Designer Workflow. It works fine for more than one month. Yesterday we got an error message:
Coercion Failed: Unable to transform the input lookup data into the requested type.
The Workflow has one people picker column, one lookup column and 4 text columns.
We work in our WF with the "collect data from user" and add this information to a field in our list. Therefore I checked all 'column types' in the Workflow and in my list but there no differences in the column types. I deleted the workflow step and create it new. It works 4 times without an error and now we got the error message again.
Did anyone of you can help me? I've no idea how to handle this problem. I'm very thankful for every advice.
