JsonParseException : Illegal unquoted character ((CTRL-CHAR, code 10)
This can happen if you have a newline (or other control character) in a JSON string literal.
{"foo": "barbaz"}If you are the one producing the data, replace actual newlines with escaped ones "\\n" when creating your string literals.
{"foo": "bar\nbaz"}
Using
mapper.configure( JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS.mappedFeature(), true);See javadoc:
/** * Feature that determines whether parser will allow * JSON Strings to contain unescaped control characters * (ASCII characters with value less than 32, including * tab and line feed characters) or not. * If feature is set false, an exception is thrown if such a * character is encountered. *<p> * Since JSON specification requires quoting for all control characters, * this is a non-standard feature, and as such disabled by default. */Old option JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS was deprecated since 2.10.
Please see also github thread.
On Salesforce platform this error is caused by /, the solution is to escape these as //.
