Research direction
Start at DefaultCodegenConfig.fromSecurity and follow its callers in DefaultGenerator.processSecurityProperties and Generate.run. Reproduce the failure with the missing OpenAPI definition and inspect the bearer security configuration. Done requires identifying the unsupported or malformed OAuth2 flow and documenting the required input or correcting the handling.
