Linking to Manager Accounts

[Kirtan Pawar]

We were implementing linking the Manager Account to the Client account

(LinkingToManagerAccount)

I already have one Test manager account (M1) and a Test client account (C1) under the M1. So to Implement the above Linking I created another test manager Account (M2) and Test client account (C2) under M2. Now I am trying to link C2 with M1. We are building a web app with the MERN stack (Javascript).

Here customerId2 is C2 and loginCustomerId is M1

I Got a response as Undefined
