Ok I narrowed down this bug I get with 3.2.2 to TJSONParser.
I’m so confused as to what changed. FormatJSON prints the JSON as expected but
AsString crashes and gives the error I was seeing from the RPC which it trapped
as an exception. When it’s send across the RPC layer it must call AsString and
then blow up thus giving me this error.
The JSON in question printed from FormatJSON is valid and can be opened in a
JSON editor even so I know it’s ok.
===========================
Request := TJSONParser.Create(Content, DefaultOptions).Parse;
writeln(Request.FormatJSON); // this prints the JSON correctly (Request
ClassName is TJSONObject)
writeln(Request.AsString);
gives this error:
An unhandled exception occurred at $00000001050261A7:
EJSON: Cannot convert data from object value
Of course, as AsString will not work on a TJSONObject.
AsString will only work on the simple types, not on the object or array types or null.
