Sometimes in the exported error log an error is reported regarding a variable value that is being expanded in an action, but the log only lists the variable name and not the expanded values. Having an optional block added to the log with a full variable dump at the time of the error would be helpful... TJ

Hi TJ,
If the error causes the project to fail then you can add a ‘Log Variables’ action to the OnFailure action list to log all variable values at the time of the error.
Regards,
Paul.
