Current Behavior

after running yarn lint getting error 0:0 error Parsing error: Cannot read property 'map' of undefined. Build and test commands work fine.

Additional context

Tried the same in Create React App, seems to be working fine.

Any ideas on this @jaredpalmer ?

Same for me : this kind of workaround didn't work ( https://github.com/formium/tsdx/issues/926#issuecomment-751936109 ) either

I dont wirte 'map' in my file, so i cant understand why i have such a problem. And i dont find any way to fix it. i just replace it with 'eslint' finally.

I am encountering this issue, too. It's a bit of a pain given that lint runs in the github actions. It's a parsing error, so my instinct was to switch the parser to @typescript-eslint/parser but that hasn't done the trick.

This is the corresponding SO question.

The workaround is to not use tuple types, or move over to a package that is not stale like dts-cli.
