Don't crash if some (but not all) Error Codes are loaded

[ArioA]

Problem

I call loadErrorMessages() but not loadDevErrorMessages() on application startup. When a "dev" error code is encountered, I get the following error:

| TypeError: Cannot read properties of undefined (reading 'message')
|     at handler (.../node_modules/@apollo/client/dev/dev.cjs:613:41)
|     at getErrorMsg (.../node_modules/@apollo/client/utilities/globals/globals.cjs:85:44)
|     at Function.warn (.../node_modules/@apollo/client/utilities/globals/globals.cjs:48:16)
|     at Object.useSubscription (.../node_modules/@apollo/client/react/hooks/hooks.cjs:550:63)
|     ...

Proposed Solution

It seems reasonable for unloaded error codes revert to the fallback, rather than causing the app to crash.
