S3-Compatible and Google Bucket

I am trying to connect Google Bucket to UpdraftPlus Backups. I’m getting an error:

S3-Compatible (Generic) settings test result: Failure: We successfully accessed the bucket, but the attempt to create a file in it failed. Please check your access credentials. (UpdraftPlus_S3::putObject(): [InvalidArgument] Invalid argument.)

But I successfully can connect with aws/aws-sdk-php.

I am using:

• https://storage.googleapis.com as S3 end-point
• s3generic://bucket-name as S3 location
• Provide valid S3 access key and S3 secret key
