I recently upgraded to 2.1 and ran a workflow using the Create Volume cmd in my test environment and got the following error message: "'_x001B_', hexadecimal value 0x1B, is an invalid character. Line 1, position 113."
Running the same workflow on a different array will run successfully but I'm just curious about the error condition in case it will appear in my production environment. Command log is as follows (I removed the names of my systems):
09:24:46.532 INFO [null] ***** Workflow Execution Started *****
Do the credentials for the array have any special characters in it? I've found some values are not escaped properly, including fairly basic characters like $ as a first character. Try changing the admin credentials for the array to alpha-numeric only and see if it helps. (and setting the new credentials in the credentials tab). Or create a second admin user with a simpler password to test if that's the problem.
The 0x1B is the Escape character so I'm assuming that's not actually in the credentials its trying to use. If it got past the credentials step I would expect to see a log for "Creating a new volume.....", so assuming the volume didn't get created and the failure is for options setting.
