Error in TTMSMCPCloudAIService when uploading a png image to Claude API

DEV TMS AI Studio

I use TTMSMCPCloudAIService component with Claude API to extract data from an invoice file.

When I try to upload a png image to Claude API, I get the following error
{"type":"error","error":{"type":"invalid_request_error","message":"messages.0.content.1.image.source.base64: The image was specified using the image/jpeg media type, but the image appears to be a image/png image"},"request_id":"req_011CZv4wpU8GBYp4eb8CMz3Z"}.

I have successfully uploaded other file types to Claude API, like jpg and pdf, without problems.

The method TTMSMCPCloudAI.BuildPostData, in unit TMS.MCP.CloudAI, has the following code
...
AUserContentParts := AUserContentParts + ',{"type":"image","source":{"type":"base64","media_type":"image/jpeg","data":"'+FFiles[i].GetData+'"}}';
...

This code uses "image/jpeg" without checking the actual image type of the file.

If I change that line to "image/png", the file is successfully uploaded.

So it seems there is a bug in this method. I don't know if there are other methods that can also have this issue.
Thanks in advance

Thanks for reporting.
We'll extend this as it seems Claude newer APIs became more picky about this.
Next update of TMS AI Studio will address this.
