@angelitoTalens did you get to the bottom of this?

This is working fine for me in v7, how did you setup your in memory data service?

[angelitoTalens]

@hungerregnuh

mock-api.service.ts

export class MockApiService implements InMemoryDbService {
createDb() {
let login:{email:string, password:string}[] = [{
email:'first.last@gmail.com',
password:'pwd'
}];

return {
login
};
}
}

In app.module.ts

imports: [
...
environment.production ?
[] : HttpClientInMemoryWebApiModule.forRoot(MockApiService, {post204: false, post409: true, dataEncapsulation: false})
],

@angelitoTalens

could you try this instead?

createDb() {
  const login = [
    {
      id: 1,
      email: 'first.last@gmail.com',
      password: 'pwd'
    }
  ];

@hungerregnuh

your suggestion worked for me.

let userCredentials = {email: email, password: password};
return this.http.post<boolean>(apiUrl, userCredentials, options)

Encountered this error:
body:error:"Collection 'inputparams' id type is non-numeric or unknown. Can only generate numeric ids."
status:422

when doing a post using:

Angular 7
angular-in-memory-web-api
const url = ${this.apiUrl};
return this.http.post(url, JSON.stringify( param), httpOptions).pipe(map(this.serviceHelper.extractData))
.pipe(catchError(this.serviceHelper.handleError));](url)

here is what the "param" consists of
common: OEGenericInputParameter;
fleet: OEInputParameterWideBody[];
optional: OEInputParameterOptions;

User gives details in the form
all the details are clubbed and made as param model
createDB(){
const inputparamsfun = () =>{
what to be given here?
}
}
