Swagger-codegen: [Typescript-angular] responseType not set on Blob type responses

Created on 7 Nov 2019 · 2Comments · Source: swagger-api/swagger-codegen

Description

If response is a blob (in schema defined with type string, format binary), the generated service fails to consume renspose (it tries to parse binary repsonse as blob):
typescript return this.httpClient.get<Blob>(`${this.basePath}/api/Image/DesignPreview`, { params: queryParameters, withCredentials: this.configuration.withCredentials, headers: headers, observe: observe, reportProgress: reportProgress } );

We are transitioning to aspnetcore3, with that we need to transition to swagger-codegen-cli-3.0.13
This issue did not exist in cli-2.4.1-SNAPSHOT with schema v2
