Spring Boot: HttpMessageNotReadableException: JSON Parse Error - Unexpected Character (')

This warning indicates a problem parsing JSON data. The specific error message, 'Unexpected character (')', suggests that a single quote (') was encountered where a double quote (') was expected to start a field name. This issue arises from incorrect JSON data formatting.

JSON (JavaScript Object Notation) is a commonly used data exchange format that represents data using key-value pairs. In JSON, field names must be enclosed in double quotes, not single quotes.

The error message provides additional information, including the location (line and column) where the error occurred. In this case, the error occurred at line 2, column 6.

To resolve this issue, you need to carefully examine your JSON data and ensure that all field names are enclosed in double quotes. If you are using a string to represent JSON data, make sure the string itself is enclosed in double quotes.
