"Temporary Redirect" Error when trying to retrieve metadata

[jacintohyd]

I have been trying to setup the package in a sandbox in my company. After struggling with the callback URL, I was able to configure the Oauth and ready to work. I gave my user the permission set included in the package and accesed the App Exec-Ray.
When trying to get the metadata, for example using the Refresh button or selecting an Object, I get the following error:

"Error. Temporary Redirect"

Steps to reproduce

1. Create a sandbox.
2. Install the package in the sandbox and configure the Auth Provider.
3. Remember to give yourself the permission set just in case
4. Go to Exec-Ray tab
5. Try using the Refresh button
6. Toas appears with error "Temporary Redirect"

I have been doing some research and this seems to be caused by receiving the status code 307 in the requestMetadata method in the ToolingApiFetcher class (line 64). I am not sure why the response is returning a redirect, but is either know why or add some lines to replace the endpoint by the one indicated in the Location header of the response.

I will try to attach the debug log so you can inspect it.
