netrc auth is not supported in scripting yet

Error message

netrc auth is not supported in scripting yet

What it means

Not-implemented guard in toPreRequestAuth (the reverse conversion, script auth model to pre-request options): the auth type is 'netrc', which cannot yet be serialized for the pre-request scripting runtime. Any script producing netrc auth hits this TODO path.

Solutions

  1. Avoid netrc when scripts mutate the request
  2. Use basic or bearer auth instead
Defensive patterns

Strategy: fallback
