crc32 checksum error when uploading a file

[marcorichetta]

Hi! I was trying this library because I thought it was a very good abstraction for uploading files to S3 :mindblown:
I followed the setup steps and when I tried to upload a file I got this error.

<Error>
	<Code>InvalidRequest</Code>
	<Message>
		The upload was created using a crc32 checksum. The complete request must include the
		checksum for each part. It was missing for part 1 in the request.
	</Message>
	<RequestId>XXW9QFD18YFBP7P3</RequestId>
	<HostId>Z9OS15MhlDZu8GKp9tQI8PCRjuzSuMR33fyp6TlQE8drPbmLOyVxgF7uccB9W4Byad0Ge/RhMBI=</HostId>
</Error>

I did some research and found this announcement from AWS aws/aws-sdk-js-v3#6810 (comment) ⚠️ It could be the cause of errors with Cloudflare R2.

---

Inspecting the requests that are sent in my example, I see that both have the required headers.

x-amz-checksum-crc32: tycIGw==
x-amz-sdk-checksum-algorithm: CRC32

x-amz-checksum-crc32: PIUedw==
x-amz-sdk-checksum-algorithm: CRC32

The only one that do not includes them is the first request, the one that starts the MultiPartUpload

I'm putting it here in case someone else is in the same situation. 🙌

Same error here. Do you know how to solve it?

[marcorichetta]

@iescude Not really. I ended using presigned urls generated from the backend and uploading directly to S3 from the client with axios.

In the linked issue to the AWS sdk it seems they found a workaround but not for Nextjs

I got the same error. Some files are working, but some other files not.
