Description

Sometimes, the server doesn't implement the response as expected, so we should hand e this.

We should add a browserParsingMethod property into the network config:

• all - the current implementation, default in order to not break backwards compatibility
• json - parse only application/vnd.api+json and application/json responses, ignore the rest
• strict - parse only application/vnd.api+json responses, ignore the rest
