Unable to mount S3 compatible bucket

[matthewblott]

I'm trying to mount an S3 compatible bucket hosted with IDrive. I can attach a bucket to a folder using rclone without any issues. However, I am unable to do the same with goofys. My credentials appear correct (as far as I can tell). The contents of the $HOME/.aws/credentials file are:

[default]
access_key_id = <my bucket key>
secret_access_key = <my bucket secret>

And the goofys command I'm using to mount is:

goofys --endpoint https://the-correct-prefix-idrivee2-the-correct-suffix.com bucket-name /mount/path

But I get the following error:

One thing I noticed is I'm receiving a 403 error because it appends [default] to the mount point which isn't required for IDrive. Other than that, I'm at a loss. I've had a good look through the issues to see if I could find any pointers for other S3 compatible providers but there's not much to go on. Any help appreciated :-)
