apollo-server-lambda: TypeError: Cannot read property 'endsWith' of undefined

Using the playground, when try to load the page, this error is outputed:

TypeError: Cannot read property 'endsWith' of undefined

Seems to be the case of not every time or at least not at the first request that the event have the path attribute.

https://github.com/apollographql/apollo-server/blob/66f48b88e0d9c8eef123154a3c7dd36a48320fbb/packages/apollo-server-lambda/src/ApolloServer.ts#L176

I printed the event object and could not find the path attribute.

Good to know! Thanks for double-checking.

Uh-oh, this looks like a regression in v2.21.1 from #4892. I bet a little question mark should fix that up.
