New DAP issue: invalid_client

[reynlds]

I did get one full initdb across all tables yesterday afternoon after the "middleware fix" (2023-10-25). However, today when I wanted to start a full syncdb on those same tables I got this:

$ dap syncdb --namespace canvas --table accounts

I checked the latest version of the DAP client and it's not changed (0.3.15). Also, my credentials have not timed out (token is good for several months).

@JozsefKercso It was suggested that I tag you on this. Also, it happens on every DAP action including "list".

[JozsefKercso]

Hi @reynlds ! We are investigating the issue... Please bear with us. Thank you!

[reynlds]

My frustration got the better of me just a few minutes ago and I generated a new identity key and plugged it into my DAP configuration. It's working now, even though my original key doesn't expire until April, 2024. Obviously, something is not right with the identity process.

FYI...this happened again on a key that should not have expired until April, 2024. What's going on?

It happened to me since February 9, 2025
