Try this:

  1. Check API Endpoint:

    • Ensure that the API endpoint you are calling is correct. Verify that the URL, parameters, and method (GET, POST, etc.) are properly configured.

  2. Inspect Request and Response:

    • Use tools like Postman or curl to test the API endpoint manually. This way, you can observe what the API returns directly and confirm if the issue lies with the API itself or with how the mobile app processes the data.
    • Look for correct headers (like Authorization or Content-Type) and ensure they are set correctly.

  3. Review API Documentation:

    • Check the API documentation to see the expected structure of the response. If the API documentation states that certain parameters or body data are required, ensure these are included in your request.

  4. Handle Empty Responses:

    • In your UiPath workflows, make sure there is error handling in place for empty responses. For instance, you can add conditions to check if the response contains data before proceeding.
    • Use a Try-Catch activity to gracefully handle cases where the response does not meet expectations.

  5. Log the Output:

    • Utilize logging in your workflows to capture responses. Use the Log Message activity to log the output of the API call. This can help you identify if the API is returning an empty array or an error message.

  6. API Rate Limits:

    • Some APIs have a rate limit that can lead to denied or empty responses after many successful calls. Verify if you’re hitting any rate limits by consulting the API documentation or contacting support.

  7. Authentication Issues:

    • Ensure that your authentication tokens or credentials are valid. Expired tokens or incorrect credentials can lead to unauthorized access and result in empty responses.

  8. Check for Filters or Query Parameters:

    • If you are using filters or query parameters in your request, verify that they are correct and not filtering out all results. Try removing any filtering to see if the API returns data.

  9. Debugging the UiPath Workflow:

    • If the API call is part of a larger UiPath workflow, step through the workflow in debug mode to identify where it might be failing.
    • Ensure that variables used to capture the response are initialized and assigned properly.
