Cannot read property 'services' of undefined

[Hanzofm]

Hi,

I am using this library(v0.6) into a Ionic v4/Angular 8 project. First:

When I try to create a client, your docs says this:

this.soap.createClient('assets/calculator.wsdl').subscribe(client => this.client = client);

But into my installed version the createClient method returns a Promise

If do a create client with a promise the method returns this exception:

TypeError: Cannot read property 'services' of undefined

What I am doing wrong?

Hi did you manage to solve this?

I am experiencing same problem. Once build in production mode, this error comes to me in run time. Any fixes for this?
