Hi all, I’m running into an issue with the Java Snippet. If I run a workflow with a POST Request or PATCH Request, the column Status is automatically created. However sometimes I do not have any rows to update, so the POST/PATCH Request don’t run. When 1 of them does not run, the Status column is not created and my Java Snippet fails, this eventually results in my entire workflow failing because I depend on a concatenation to summarize my results via email. What’s the best way to detect and add a missing column? Here’s an example workflow… POST and PATCH Test.knwf (16.8 KB)
