After recent update, I get the following error. and some of my users claim they cant update whitelisted files. Aws::S3::Errors::NotImplemented (A header you provided implies functionality that is not implemented) /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/aws-sdk-core-3.48.6/lib/seahorse/clie…

Is your S3 bucket on Amazon S3?

No. I’m using my own minio server.

Then the error is fairly self explanatory. Discourse is using an S3 feature that minio doesn’t implement.

yes. but what is it? and how can I disable/fix it?

Your best bet is to look at recent commits having to do with s3

As far as I see the newest change that I didnt have is secure upload feature that I have it turned off in my forum. :confused:

any suggestions? more ppl are reporting this issue.

If I upload a picture, it doesnt let me to publish the post by throwing internal server error. However i can cut the uploaded picture url, publish the post, edit post and add that url, and publish it again.

Please give us the full backtrace of the error.

here it is : /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/aws-sdk-core-3.48.6/lib/seahorse/client/plugins/raise_response_errors.rb:15:in `call' /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/aws-sdk-s3-1.36.1/lib/aws-sdk-s3/plugins/sse_cpk.rb:22:in `call' /var/www/discourse/vendor/bundle/ruby…
