With external browser authentication the driver caches an ID token (clientStoreTemporaryCredential) so the browser is opened only once. When that token expires the driver keeps sending it instead of starting a new authentication, so every process fails with: Snowflake connection error: The provided ID Token is invalid. and the only way out was removing the credential cache file by hand. The executor now detects that failure (GS error 390195 / "ID Token is invalid"), removes the cached ID token and retries the connection once, which starts a new browser authentication. A warning is logged in the Runnerty output: warn: execute-snowflake: The cached SSO ID token has expired. Removed it and re-authenticating through the browser... Re-authentication is shared between the processes of an execution: when a chain runs several Snowflake processes in parallel they all fail at the same time, and without coordination each one would open its own browser window and the extra ones would die with "Browser action timed out". Only the first process authenticates, the rest wait for it and reuse the newly cached token. Only the external browser flow is affected: any other connection error, and the OAuth token flow, keep the previous behaviour. The snowflake-sdk internals used to drop the cached credential are required lazily so a future change in the driver cannot prevent the executor from loading.
