Type error in the terminal: Received an instance of Uint8Array

[ashkan-ahmadi]

Describe the bug
I recently upgraded my Supabase CLI to v2.75.0 and when I serve my functions, none of my existing functions run and I constantly get this error of "Invalid JWT" even though nothing has changed and I'm using the correct JWT. In the terminal, I get this error:

from qiao:

Could you try restarting from scratch? supabase stop --no-backup && supabase start

Log into your account to get the access_token in the JWT and use that to send requests to your edge functions

I'm assuming you are talking about the personal access token? You want to use the publishable key shown from supabase status command. Here's an example https://github.com/supabase/cli/blob/develop/tests/edge-runtime.sh#L7

@sweatybridge Thanks Yes, my issue is that in the new cli version, I cannot easily validate the JWT like I did before. As you can see here as an example of edge function I have https://pastebin.com/v1nRVMf0 I'm struggling to refactor my code to use the new JWT validation system
