Here, conversion happens on the previous OneDrive too. Do you have an authid field there if you Export as Command-line? If not, you might just not have a colon to do percent-encoding on. Such encoding is common in URLs. This URL is for target/storage/connection and is explained here (pointing back to its reference here).
By the way, the AuthID is an access secret, so if you posted it, please get another unless that one’s redacted.
I think what @JonMikelV was trying to ask was how you’re using this. The intended use, as its name implies, is to run at a Command Prompt. Does that work? It sounds like you copied authid out manually to other spots and found authid doesn’t drop right in, but arguably it shouldn’t – URLs sometimes need percent-encoding…
If you need to copy the authid, try getting it from the AuthID field of the UI, or better yet, your password saver.
The GUI AuthID form is the one with a colon that GUI and other work requires, and the “%3A” is the URL form.
