eslint-formatter-sarif "suppressions" can include duplicate items that causes sarif uploading issues

[martgil]

Hello Team,

I'd like to report an issue when the eslint-formatter-sarif suppressions can include duplicate items from which uploading sarif files to fail.

Error we received on https://github.com/FlowCrypt/flowcrypt-browser/actions/runs/9240112388/job/25420029132:

Rrror in plain text:

So for us to proceed into fixing the issue temporarily on our side, we'll have to update the code for populating the suppressions - FlowCrypt/flowcrypt-browser@876c442#diff-309b09cf37242b8d5d9b63644d18bb3b386d6dc257ea0be89f3fff0e61718979R196-R216

Other than this, the formatter is working so well. Thank you!
