That's odd, that dependency should have been installed during the dependency installation when the plugin first ran - it requires you to click "Install dependencies". Can you try uninstalling the plugin, re-installing it, and watching the terminal output during dependency installation to check for any errors?

I'm having the same

Internal client error
No module named 'pyjwt_key_fetcher'

I've done the Install dependencies procedure and reinstalled twice, but it keeps showing up.
Same as the first guy, the error pops up right after I click CONFIRM AND GIVE ACCESS

Has any fix been made yet?

Thanks for adding your report to this issue. It seems you and a few others are experiencing this, but no exact cause has been identified yet,

@pluh01 Could you also please try the above step to get more info from the error, e.g. try uninstalling the plugin, re-installing it, and watch the terminal output during dependency installation to check for any errors?

To enable the terminal:

• On Windows, in Blender go to Window > Toggle System Console to see the console.
• On Mac OS, you'll need to start Blender from a terminal window.

My antivirus also gives me a warning when downloading dependencies, but I always unblock the file. Should I give it a try with my antivirus completely disabled?

SOLUTION FOUND

While you are installing dependencies you have to completely disable your antivirus if you're encountering this issue, the antivirus blocks out the pyjwt-key-fetcher module during installation and it won't work even if you exclude it.

Thank you for sharing the output! To put any concerns at ease, pyjwt-key-fetcher is not malicious - it is a valid required dependency of the plugin that is supposed to be installed when the plugin first runs. If your antivirus is blocking it, it will cause this issue, and you need to disable your antivirus during installation, or otherwise prevent it from blocking this.

pyjwt-key-fetcher is used here to use the kid property of the id token to look up the corresponding public key from Roblox's certificate endpoint, which is then used to verify that the id token was signed by Roblox. The pyjwt-key-fetcher library simplifies this fetching and key matching down to a simple single function call.

I'm closing this issue as completed, but opening a new ticket to track the bug allowing the plugin to get into a bad state with partially installed dependencies after a failed installation.
