Some observations:

* it seems your package.json is still from an old iteration: https://github.com/saml-to/assume-aws-role-action/blob/main/...

* it was super opaque where this relative import comes from: https://github.com/saml-to/assume-aws-role-action/blob/main/... but after some sniffing around, it seems to be some openapi generation magick https://github.com/saml-to/assume-aws-role-action/blob/main/... against one of your own API endpoints https://github.com/saml-to/assume-aws-role-action/blob/main/... which seems to mean that using this toy is not "self contained" in the way that `sts:AssumeRoleWithWebIdentity` is
