S3 Ressource "Wasabi Hot Storage" uploading files does not work. - Error: "AuthorizationHeaderMalformed"

I successfully connected my Wasabi Hot Storage as Resource.
I can list all the files and folders and show them in a table.
But when I try the Upload File query of the ressource I get the error "AuthorizationHeaderMalformed .... Credential is not in five parts".
I followed this guide Query S3 data | Retool Docs but cant make it work.

Has anybody solved this issue?

Hey @ben10, unfortunately not every 'S3-compatible' cloud storage provider is completely compatible. I wasn't able to dig up much on that exact error. Are you able to see what a successful upload request looks like in Wasabi vs what is received when the upload is sent from Retool?
