comalibabafastjsonJSONException expect at 0 actual =

This error message suggests that there is a JSON parsing error. The parser was expecting a colon (":") character at position 0, but it encountered a different character instead.

To resolve this issue, you need to check the JSON data that you are trying to parse and make sure it follows the correct syntax. Specifically, ensure that all key-value pairs are separated by a colon and that the JSON is well-formed.
