I tried configuring my workflows to use GO as the transfer protocol. I had no issues creating a directory on Summit, but when the local directory creation job tried to run using the CARC endpoint, I got the following error:

Traceback (most recent call last):

I had previously authenticated using the Globus website to both the OLCF DTN and the USC CARC User Directories endpoints, and then ran pegasus-globus-online-init, went to the website, and entered the code. (BTW, I ran into an error in pegasus-globus-online-init.py; config.set() expects strings but some of the values were ints, so I just wrapped them all in str()). However, it seems like the authentication isn't working for some reason. Since the example on the documentation uses the hash notation, I used the extremely human-readable "u_aieoitmpvnbchfh6dhsxvaiarq#b92e5d86-0d7b-11eb-8938-0a5521ff3f4b" for the CARC endpoint (it's the 'Legacy Name' on the endpoint info page). This particular job is /home/shock/scottcal/runs/USC_Integrated_dax/run_7218/dags/scottcal/pegasus/CyberShake_Integrated_USC/20211113T234036-0800/create_dir_CyberShake_Integrated_USC_0_local.sub.

Thanks for your help!
