I am attempting to write a workflow that will copy a newly created list item from a list on a subsite to a logging list on the parent site. I must have done something wrong because my workflow is showing as complete but not copying the data and logging a BadRequest error in the workflow log. unhelpfully, it is not telling me anything more about the nature of the bad request. Does anyone know how I can access the full error message?
You could use fiddler to test the REST API. For more detailed information, refer to the article below.
And you also could check the characters in the call http web service action are correct. For more detailed information, refer to the article below.
