A RuntimeException occurred because a JSON parser detected an illegal unquoted character (CTRL-CHAR, code 10). This control character must be escaped using a backslash to be included in a string value. The error originates from the Jackson library’s JsonParseException and points to a location in the input string at line 1, column 567. The parser was invoked with StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION disabled, so the error message includes the exact location of the problematic character. The exception stack trace shows the chain of causes: a RuntimeException wrapping the JsonParseException. This issue typically arises when reading multi-line JSON strings without proper escaping. Developers should ensure that control characters such as line breaks are represented with escape sequences like ‘n’.
