Error Description:
A critical issue has been reported where the tRPC authentication context fails to validate the session token, resulting in a signature mismatch on the JWT decrypter.

Module Affected:
packages/trpc/server/context.ts

Line: 12

Error Code: JWT_SIG_INVALID

Impact:
This error is causing authentication failures in the API route, preventing the tRPC context from returning a valid tenantId.

Steps to Reproduce:

  • Trigger an API call requiring token validation in tRPC.
  • Observe the failure in token signature verification.

Severity: Critical

Please investigate and resolve at the earliest. This task is assigned to @ahmadjavaiddev due to his expertise in related commits.

                          Error Code: JWT_SIG_INVALID
                          Impact:
                          
This error is causing authentication failures in the API route, preventing the tRPC context from returning a valid tenantId.
                          Steps to Reproduce:
                          • Trigger an API call requiring token validation in tRPC.
                          • Observe the failure in token signature verification.
                          Severity: Critical
                          Please investigate and resolve at the earliest. This task is assigned to @ahmadjavaiddev due to his expertise in related commits.

A critical issue has been reported where the tRPC authentication context fails to validate the session token, resulting in a signature mismatch on the JWT decrypter.

                              packages/trpc/server/context.ts
