This upload url should comes from this line of code
Copy code
<Error>
<Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message>I got this error…
my initial guess is this related with these 2 setting? I just makeup 2 random string to set these 2 env values. Am’I wrong?
@fresh-football-47124 I suggest you to change the s3 upload using the v4 version
https://github.com/aws/aws-sdk-js/issues/1213#issuecomment-259261766
Copy code
var s3 = new AWS.S3({signatureVersion: 'v4'});f

@helpful-carpenter-3208 Does your AWS bucket policy require a specific signature version? According to the docs, both v2 and v4 and allowed by default unless you restrict the signature version in the bucket policy. https://docs.aws.amazon.com/AmazonS3/latest/API/bucket-policy-s3-sigv4-conditions.html
I see, looks like v2 is deprecated and any new buckets created only support v4. I'll update our api to use v4 when signing the url.

03/11/2022, 4:48 AMHi, @future-teacher-7046 I can see you have made the change and it indeed use the v4 signed url. but I’m still got 400 error…
I’m wondering if something else I’m missing on our bucket

is it just through Growthbook?
can you access the files directly?
h
helpful-carpenter-3208
03/11/2022, 5:00 AMYes, it’s through our selfhosted growthbook. the file is not uploaded to our s3 bucket.
this 400 request is mean to upload the file to s3. but got 400
