Why PDFDocument.load() is not working with lambda ?

[parthshah27]

I have created a lambda function in which I'm passing the public URL of the pdf file which is located in s3. I'm converting that file to buffer and passing that buffer data to load() function but It throwing an error. "The "chunk" argument must be of type string or an instance of Buffer. Received an instance of Uint8Array". Please check the below code to get a better understanding.

const existingPdfBytes = await axios.get("https://yamaha-finance.s3.ca-central-1.amazonaws.com/zip/dummy.pdf", { responseType: 'arraybuffer', headers: { 'Accept': 'application/pdf' } }); console.log("[BUFFER DATA]",existingPdfBytes.data); var bytes = new Uint8Array(existingPdfBytes.data); const pdfDoc = await PDFDocument.load(existingPdfBytes.data);

    Above is the code which I'm trying to execute and below is the error which I'm getting

Does anyone have an idea how to resolve it? Same code is working fine in local

const s3 = new AWS.S3();
const { Body } = await s3
          .getObject({
            Bucket: 'bucket',
            Key: templateObjectKey,
          })
          .promise();

const pdfDoc = await PDFDocument.load(Body as Buffer);

works for me
