Backblaze as Remote error Unsupported header 'x-amz-checksum-mode' received for this API call.

[mguimond]

@DustinB That is correct.

[DustinB]

@mguimond Could be a bug in a recent release, @Danp are you aware of anything?

[Danp]

@DustinB No, but dev team has been notified so that they can investigate.

I submitted this as a GitHub issue last week.

TL;DR: Backblaze aparently doesn't support those flags that are enabled by default
"Backblaze does not yet accept these headers, so we recommend downgrading to AWS Javascript 3.x SDK version 3.728.0."

@jr-m4 nice find . thank you

[florent]

@mguimond @jr-m4 I would like to be able to keep the library up to date.
Would it be possible to patch a file in your install ? and check if the backup run It will disable the checksum computation .

Note that if you use backup encryption, the checksum are already checked on restore

you can either use this branch : fix_s3_backblaze or modify directly the code in your installation in <xo>/node_modules/@xen-orchestra/fs/dist/s3.js

replace :

 requestHandler: new _nodeHttpHandler.NodeHttpHandler({
        socketTimeout: 600000,
        httpAgent: new _http.Agent({
          keepAlive: true
        }),
        httpsAgent: new _https.Agent({
          rejectUnauthorized: !allowUnauthorized,
          keepAlive: true
        })
      })

by

 requestHandler: new _nodeHttpHandler.NodeHttpHandler({
        socketTimeout: 600000,
        httpAgent: new _http.Agent({
          keepAlive: true
        }),
        httpsAgent: new _https.Agent({
          rejectUnauthorized: !allowUnauthorized,
          keepAlive: true
        })
      }),
      requestChecksumCalculation: "WHEN_REQUIRED",
      responseChecksumValidation: "WHEN_REQUIRED"

(the difference is

,
      requestChecksumCalculation: "WHEN_REQUIRED",
      responseChecksumValidation: "WHEN_REQUIRED"

I (previously as @jr-m4) just tried the patch you suggested. And I can confirm that this does indeed make the backup complete successfully!
Great work finding a solution that quicklly!

[olivierlambert]

Great example on how great the community is and how fast our dev can fix it! Thanks for the feedback, it really matters, as you can see!

[florent]

thanks for pointing the exact issue in the aws SDK. It gave use enough matter to find the fix

[mguimond]

@florent Sorry for the delay. I was able to make it work with the change you posted. Thank You.
