Signed upload (post) to object storage

I have an High Performance - S3 object storage setup. Everything is working as expected. We are using node.js and react frontend.

I am now looking into allowing upload directly from our frontend using signed post:
https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/Package/-aws-sdk-s3-presigned-post/

I am using `@aws-sdk/s3-presigned-post`in the backend to create a pre-signed post request. And this seams to work and I receive an request with an URL and several fields. I then create a form-data post request using postman to test the file upload. I send the post request to the URL and include all the fields from the response. But I get the error below. Is this feature not supported on OVH or am I doing something wrong?
