Failed to get or set session config

What it means

FrontendError::SessionConfig, converted from SessionConfigError: getting or setting a session configuration variable failed, e.g. unknown variable name or a value that cannot be applied to the session. Raised by the session-config access path.

Solutions

  1. Inspect the wrapped SessionConfigError for the failing parameter name or operation.
  2. Verify the parameter exists and the value type/range is valid (see SHOW PARAMETERS).
  3. Ensure the session is valid before getting/setting configuration.
