Feature: Support Storing Access Tokens >255 Characters in Connection Metadata for Enterprise Connections
Description:
We are using a Google Workspace Enterprise connection where a service account access token is stored in the connection metadata field (gAdminAccessToken). Recently, Google started issuing access tokens exceeding 255 characters.
Since Auth0 enforces a 255-character limit on connection metadata values (per your documentation), this is causing token truncation and failures in profile sync during login.
We request either:
Increasing the allowed size limit for metadata values.
Or providing a secure alternative method (e.g., encrypted secrets linked to a connection).
This is a critical blocker for scenarios where third-party identity providers (like Google) can issue variable-length tokens exceeding this boundary.
