Windows Path problems with paws sts.

[ssefick]

Hello, I have used the saml authentication example as inspiration for a few functions to authenticate, and write to the credentials file.

I developed the on *nix, so I didn't find this issue until helping a colleague today on a windows machine.

sts seems to be mangling the path when trying to find .aws/config and .aws/credentials.

Like this C:\Users\name/.aws/config. Please let me know what else I can provide to help.

Any thoughts?

When you say the path is getting mangled what do mean? For window machines paws looks in the USERPROFILE directory. This is recommended by aws file location.

Can you provide example of the mangled path please?

Yes, the errors are saying that the config and credentials files do not exist at a path like:

C:\Users\name/.aws/config

It looks like the path is a mix of back slashes and forward slashes.

Please let me know if you need anything else.

Interesting:

The first part C:\Users\name is coming from USERPROFILE environmental variable. From memory window machines don't like a single \ and prefer a \\ instead.

The second part /.aws/config is coming form the base R function file.path that builds the file path using the .Platform$file.sep (this is default). I believe windows accepts / for it's file path.

For windows I would of expected something like this:

C:\\Users\\name/.aws/config

It looks weird but window machines accepts this as a valid file paths 🤷

First can you double check if the .aws/config is in the C:\\Users\\name/.aws/config location. If so then I would advice making sure your USERPROFILE is set correctly.
