Error message

singleToken auth is not supported in scripting yet

What it means

Not-implemented guard in toPreRequestAuth: the auth type is 'singleToken', which the scripting environment cannot yet serialize into pre-request auth options. Encountered when a request uses single-token based authentication in a scripting context.

Solutions

  1. Use bearer auth to set a single token from scripts
  2. Wait for singleToken support in the scripting environment
Defensive patterns

Strategy: fallback
