Your issue may already be reported! Please search in the issue tracker before creating one.

Please thumbs up this issue if you have also experienced it. You may also add more information if there is something relevant that was not mentioned. However, please refrain from comments that are not constructive, like "I have this problem too", etc.

Expected behavior (required)

The GET response should return a JSON formatted table from Google Cloud Storage. (See Image for Postman response)

Current behavior (required)

The API call gives 'Status: 200 (Success)' but is null. (See image). Dropping the ?alt=media portion gives the object metadata succesfully. I believe this issue started after the v3.0 Flutterflow updates.

To Reproduce (required)

1. in FF, Define a new API Call as 'GET https://storage.googleapis.com/storage/v1/b/pool-party-e4d98.appspot.com/o/firebasetable?alt=media'
2. Test API Call

Hi, Looks like this is related to authentication issue. Have you add the authentication details in FF api call which is same as in postman?. What happens when hit the endpoint directly on a browser? Could you please confirm these details please.

[jerico-johns]

The endpoint in Google Cloud Storage is public so no auth is required. You can see Postman is not using any auth. Hitting the endpoint in browser directly (pasting the request in as URL) works without issue. Feel free to try as this is a public object in GCS.

To update I believe this issue arose after the FlutterFlow v3.3.4 updates on November 18th, 2022. I was able to hit this API endpoint within FF with no issue before that update.

Hi, I'm having the same problem when I use a variable as a parameter in the post method, it returns status 200 null

Same here... Any update on a date or version to have this fixed? It's completely blocking key functionalities.
Thanks!

Hello, Looks like this issue is specific endpoint return type. End point return formate is not as standard json formate instead it is in a sort of table formate. This is specific to firebase storage endpoint. This is not a bug. However, I can mark this as a feature request.
