C2pa(ClaimDecoding): claim could not be converted from CBOR

[mwegithub]

I'm using the latest version (from NPM) of the C2PA JavaScript library in a small project. I tried to check the CAI data for a PNG file created by ChatGPT and get the error message in the title. Call stack shows

PtcAIService.ts:170 Error reading image: C2pa(ClaimDecoding): claim could not be converted from CBOR

I use Google Chrome on Windows.

I then tried the copy of the c2patool.exe I've had (on Windows) with the image and it produced the similar error "Error: claim could not be converted from CBOR".

I updated the c2patool.exe to the latest version available here on GitHub (from May 2025) and this fixed the problem. I now can see the CAI data in the ChatGPT PNG file.

I wonder if there is something missing or outdated in the official JavaScript package that has been fixed in the c2patool?

I have attached the ChatGPT created image that produces the error.
