Hi, could you try adding import mappig config to your annotation? That seemed to work for me when I had this issue last time

@Openapi(
  additionalProperties:
  DioProperties(pubName: 'masterai_api', pubAuthor: 'DreamingCodes'),
  inputSpec:
  InputSpec(path: 'openapi/openapi.json'),
  importMappings: {
      'OneOf': 'package:one_of/one_of.dart', // <--- add this
    },
  generatorName: Generator.dio,
  runSourceGenOnOutput: true,
  outputDirectory: 'api/masterai_api',
)
class MasteraiClient {}
