After migrating from 0.19.2 to 0.20.5 typedoc is throwing error

[hassanazharkhan]

Typedoc failed to generate documentation using 0.20.5 while it is working with 0.19.2

Error:

Environment

• Typedoc version: 0.20.5
• TypeScript version: 3.9.7
• Node.js version: 14.5
• OS: Mac/bigSur

The same issue also exists in 0.20.6 which has just been tested

I really wish I could reproduce it... fixing it isn't that difficult (0.20.7), but I played around for a while and wasn't able to get the issue to show up. Is there any chance you have seen this in an open source project that I could debug?

Oh... I feel dumb now. The cause of this was the old TS version. elements was called elementTypes in 3.9.
I really need to set up a way for typedoc's tests to run on multiple TS versions to detect this sooner.
