The browser (or proxy) sent a request that this server could not understand

API

Anyone experience this issue using openai typescript package?

I keep getting “The browser (or proxy) sent a request that this server could not understand” in my AWS lambda.

Here is the code in the lambda to upload the file.

   fs.writeFileSync(
          '/tmp/test.jsonl',
          '{"prompt":"1 ->","completion":" yes\n"}\n{"prompt":"2 ->","completion":" no\n"}',
          {
            encoding: 'utf-8',
          },
        );
        const fff = fs.readFileSync('/tmp/test.jsonl');
        result = await openai.createFile(fff, 'fine-tune', {
          transformRequest: [
            ...curTrans,
            (data, headers) => {
              console.log('HW:uploadFile: request = ', data, headers);
              return data;
            },
          ],
        });

I create the same content on my local and I am able to upload it using curl. Here is the file on my local.

{“prompt”:“1 ->”,“completion”:" yes\n"}
{“prompt”:“2 ->”,“completion”:" no\n"}

Here is the request data & headers in the axios
