JSON file under Windows 10

[tester0077]

I have compiled the reader and writer files for Windows, using MSVC 2022 and I am having issues with the JSON sample file when I pass it it to the writer code.
The first 2 sections seem to be handled without issues, but the sections following simply bomb the writer with some sort of exceptions.

Unfortunately, the Adobe XMP code is not very friendly and gives no feedback regarding the possible cause(s).

While I am pleased to find that several non-English strings are used in the example, I am wondering if there is any place where one might explore and remedy these issues?

Sorry, I run Linux only and have no access to a Windows machine, so I cannot triage and debug this issue. If you can provide more information (example files, error messages, etc) I'll do my best to address it.

It has been some time and some of the details are hazy.
IIRC, the data was written to the test image, but the exception caused me to realize only much later.

To make things work as expected I had to replace the original code section

 auto j = json::parse(stdin);
 try {
 fhmwg::updateMetadata(xmpMeta, j);
 } catch (XMP_Error ex) {
   fprintf(stderr, "CRASHED with error %d:\n  %s\n", ex.GetID(), ex.GetErrMsg());
   throw ex;
 }
 file.PutXMP(xmpMeta);
 file.CloseFile();

with this bit:

auto j = json::parse(stdin);
 try {
    fhmwg::updateMetadata(xmpMeta, j);
  } catch (XMP_Error ex) {
    fprintf(stderr, "CRASHED with error %d:\n  %s\n", ex.GetID(), ex.GetErrMsg());
    throw ex;
  }
  try {
    // using this test ahead of serializing seems to avoid having an
    // exception thrown and lets the code run to completion 
    // without any hiccups.
    if( file.CanPutXMP( xmpMeta ))
    {
      file.PutXMP( xmpMeta );
    }
  } catch(XMP_Error ex) {
    fprintf(stderr, "CRASHED with error %d:\n  %s\n", ex.GetID(), ex.GetErrMsg());
  }
  file.CloseFile();
