Query variables parameter is badly serialized when using GET method in production

Intended outcome:

I would like to use a GET method to allow query caching using httpLink.create({uri, method: 'GET'})

Actual outcome:

This works correctly for development with ng serve but when built for production or using ng serve --prod the variables query parameter is serialized as [object Object] instead of {"currency":"USD"}

I can see there is a test assertion but I’m not too sure how it can be executed with production optimizations: https://github.com/apollographql/apollo-angular/blob/d185116b2d2306a40b12db747a058621211e2e92/packages/apollo-angular-link-http/tests/HttpLink.spec.ts#L205

How to reproduce the issue:

Example: https://github.com/mrfoster/ng-apollo-link-bug-1

Steps to recreate:

• ng new apollo-angular-test
• ng add apollo-angular
• Change the line in graphql.module.ts from httpLink.create({uri}) to httpLink.create({uri, method: 'GET'})
• Create a query that accepts variables

query Rates($currency: String!) {
  rates(currency: $currency) {
    currency
    rate
  }
}

• Start using ng serve --prod

@kamilkisiela It was nothing to do with name mangling. The optimisations seemed to simply remove these lines: https://github.com/apollographql/apollo-angular/blob/b9ee478b56aa7448617c9aa4d47efac4ab43dca6/packages/apollo-angular-link-http-common/src/utils.ts#L34-L38

Please bump apollo-angular-link-http-common to 1.5.1, it contains a fix
