[🐛 Bug]: JSON parsing error when creating capabilities

What happened?

When starting a session on Sauce Labs, if a user does not have sufficient VMs for their account, Sauce Labs will reply with a redirect message and (I believe) an empty payload. @shs96c I know you fixed something like this and I thought it was addressed in the RC, but the stack trace below is showing 4.0.0. Does a Redirect response need separate processing? It seems like it shouldn’t be necessary to parse the payload at all for a redirect.

How can we reproduce the issue?

It would be difficult to reproduce this without a Sauce account and running more in parallel than sessions available, but should be able to mock out a response in a unit test?

Basically, what needs to be done is to enable followRedirects option for the default HTTP client.
