Hi everyone - Iâm wondering if someone knows the trick to listing object versions in AWS S3? I was previously using a non-Zn library (there are a few around - but they are quite old and Iâm not sure how much they are maintained) - however I hadnât realised that Zn actually supports S3 until I read it a bit carefully and realised that I needed to load an extra AWS group. So - I have a bucket that is versioned, and I wanted to read the versions of an object - and hopefully be able to read the contents of an older version. I can list the contents of a bucket, but when I try to read the versions of an object - I get a forbidden error - which when I dig deeper gives a stranger explanation? I have confirmed that the AWS CLI is able to list versions in that bucket - so Iâm a bit confused what the issue might be? (client := ZnAWSS3Client new) accessKeyId: 'xxx'; secretAccessKey: âyyyyy'; checkIntegrity: true. client buckets. âWorks" client keysIn: 'mtt-dataâ. âWorks" client at: 'mtt-data' -> 'sample.txtâ. âWorks" client keysIn: 'mtt-data' query: (Dictionary with: 'versions'->nil). âGives an error?â HTTP/1.1 403 Forbidden <?xml version="1.0" encoding="UTF-8"?> <Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message><AWSAccessKeyId>xxx</AWSAccessKeyId><StringToSign>GET Has anyone tried doing this - Iâm sure there is something really simple that I am missing? Tim
