Error during work of Distance based source selection algorithm in PR #1866

[smoskaluk]

Preconditions

1.Set Distance based source selection algorithm settings on configuration page in admin (Catalog -> Inventory), select 'Google Map' as provider for distance based SSA, set proper Google API key
2. Create Test stock with two test sources with proper location data and assign it to Main website as sales channel
3. Create simple product and assign it to both of test sources
4. Place order with created simple product

Steps to reproduce

1. Open order in admin and start to create shipment for it
2. On source selection page try to apply Distance based source selection algorithm

Expected result

1. [Screenshots, logs or description]
2. Distance based source selection algorithm works properly

Actual result

1. [Screenshots, logs or description]
2. Error "A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later."
