Description
The current situation is that an incorrect JSON format returns
unexpected EOF
. This usually happens when the JSON data is not fully received or the parser reaches an unexpected end of file. This error message may not be clear enough for users to understand where the issue lies.After this PR modification, it will return a more explicit error message
invalid JSON
, indicating that the received JSON data cannot be correctly parsed into a valid JSON structure, thus providing a clearer indication of formatting issues.
