Uncaught runtime error when running DCR locally - Safari only

[sookburt]

What happened?

When running DCR locally, including the main branch, I've noticed an error which only appears in Safari. AMP pages are fine but DotCom pages all seem to throw this sooner or later. shows the error.

Where is this happening?

When running locally only and loading any article including the dev articles listed. Example: http://localhost:3030/Article/https://www.theguardian.com/cities/2019/sep/13/reclaimed-lakes-and-giant-airports-how-mexico-city-might-have-looked

What is the impact?

Likely affects devs only, when testing their code against Safari. Not seen in PROD.

Worth checking to see if this is happening in PROD

I've not seen it happening in PROD - just when running locally.
