Problem with LoopBackConfig.setApiVersion('')

[PhilippeCorreges]

What type of issue are you creating?

• Bug
• Enhancement
• Question

What version of this module are you using?

• 2.0.10 (Stable)
• 2.1.0-rc.n (2.1 Release Candidate n)
• Other

Write other if any:

Please add a description for your issue:

When the API is not versioned, if you write as suggested in your component:
LoopBackConfig.setBaseURL('https://localhost:3000'); LoopBackConfig.setApiVersion('');

an additional '/' is generated.
So the request are made towards: //Customers/login.

Sometimes APIs are not versioned and this is blocking.

Kind Regards for your help.
