Issue with File Upload API. I need an url file to send to chat API

Context

I am encountering an issue when uploading a PDF file via the API. Initially, the API required UTF-8 encoding.

Initial Error

{
  "detail": "Failed to decode data, please encode your file using UTF-8."
}

My solution

const fileContent = fs.readFileSync(
  "./public/uploads/Invoice.pdf",
  "utf-8"
);
const blob = new Blob([fileContent], {
  type: "application/json",
});
createdFile = await mistralAI.files.upload({ file: blob });

Data send to chat API

aiEngine : "mistral-large-latest"

 // stream for MISTRAL
  await mistralAI.chat
    .stream({
      model: aiEngine,
      messages: {
          role: "user",
          content: [
            {
              type: "text",
              text: "What's the content of this file ?",
            },
            {
              type: "document_url",
              documentUrl: createdFile,
              // documentUrl: "https://www.soundczech.cz/temp/lorem-ipsum.pdf",
            },
          ],
       },
      // temperature: 0.2,
      topP: 0.1,
    })
    .then(async stream => {
      for await (const part of stream) {
        if (stream === null) break;
        // Add each token to the encoded array
        encodedOutput.push(
          ...encode((part.data.choices[0]?.delta?.content as string) || "")
        );
        messageOutput.push(
          (part.data.choices[0]?.delta?.content as string) || ""
        );

        // Stream each token to the client
        res.write(`data: ${part.data.choices[0]?.delta?.content || ""} \n\n`);
      }
    })
    .catch(err => {
      return err;
    });

The next Error

 {"detail": "Invalid file format.", "description": "Found 2 errors in this file. You can view supported formats here: https://docs.mistral.ai/capabilities/finetuning. ", "errors": [{"message": "line contains invalid json: unexpected character: line 1 column 1", "line_number": 1}, {"message": "line contains invalid json: unexpected character: line 1 column 1", "line_number": 1220}]}

I dont find a solution for this on mistral API doc..

If i used a public url like 'lorem-ipsum', the chat api run correctly

A solution ?

Hey thanks for opening this issue.
We don;t support using the files api response as is.
For now, you need to get a signed url for the files

const signed_url = client.files.getSignedUrl({ fileId: createdFile.id })

and pass it as an url
documentUrl: signed_url,

I will see to add this example to our doc
