This bug is:

• Making Bruno unusable for me.
• Slowing me down but I'm able to continue working.
• Annoying.
• This feature was working in a previous version but is broken in the current release.

🐞 Describe the bug

When I try to send put request to S3 storage with a file larger than 20 MB, the app freezes (timer goes on, but app is not responding, Mac labels it as frozen) and needs to be killed

📝 Steps to reproduce

• Prepare request to s3 pre-signed put
• Select file larger than 20 MB
• Send the request

  }
}

Hi @kisljak, thanks for reporting this. We were able to reproduce the issue on our end when sending an S3 pre-signed PUT request with a file larger than 20 MB.

We’ll raise this with our engineering team for further investigation and will keep you updated on the GitHub issue as we make progress.
