The error specifically states that the JSON data being parsed was expected to be an array (starting with '['), but instead, it encountered an object (starting with '{'). This suggests that the format of the JSON data received doesn't match the expectations of the code. To resolve this issue, you need to carefully examine your code and the JSON data: 1. Validate JSON Data Format: Ensure that the JSON data you're working with is correctly formatted. Double-check the structure, ensuring that it starts with an array '[]' if you're expecting an array. 2. Review Code Logic: Scrutinize the code where the parsing occurs. Confirm that you are correctly handling the expected JSON data type. You should use the appropriate Gson methods for parsing arrays (e.g., Gson.fromJson(jsonString, List.class)). 3. Debugging and Troubleshooting: Employ debugging tools to inspect the JSON data at runtime. Examine the values in the JSON string and how they are being interpreted by your code. Use breakpoints to step through the code to pinpoint the exact line causing the error. By addressing these points, you can identify the root cause of the "Expected BEGIN_ARRAY but was BEGIN_OBJECT" error and fix it efficiently.
