API call successful but returns null value

[icestormpure]

Can we access your project?

• [X] I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

I am using ngrok to expose my local mysql server and to make api call, I am able to retrieve the values by using Postman but when it comes to Flutterflow, it returns "Status 200 (Success)" but returns null value

Expected Behavior

Should be able to show the same result as postman does

Steps to Reproduce

1. Set up express/node local API
2. Make sure local mysql server is running
3. Run the server js file
4. Run ngrok
5. Use the link provided by ngrok to make api call
6. Make postman call (Successful and returns the actual values)
7. Make flutterflow api call (Successful but returns null)

Reproducible from Blank

• [X] The steps to reproduce above start from a blank project.

Hello,

Could this issue be related to not including a userId in your request on FlutterFlow? FF operates similarly to other API tools when making requests, so this might be a configuration issue on your local server, particularly around access control and who can retrieve specific information.

Please note that this GitHub issue tracker is intended for reporting and reproducing issues directly related to the FlutterFlow platform. If you need assistance with achieving this integration, feel free to reach out to our support team via in-app chat or at support@flutterflow.io.

No it doesn't. Just try and make an api call with the full url with no variables, it'll still return null and returns status 200. This is literally a bug how else is postman able to retrieve the values

So I figured out the problem. I added header Ngrok-Skip-Browser-Warning: 'true'

Now it's able to get the data
