TypeError: value.replace is not a function

[smallmain]

The typescript file reports an error directly, but the javascript file has no problem.

maybe TypeStrong/ts-node#2000 ?

Wallaby ships with the latest official version of ts-node, v10.9.2.

The last beta available for ts-node has support for multiple extends files, which I assume is the cause of your problem.

You should be able to fix this by installing the beta version for your project: npm install ts-node@11.0.0-beta.1.

It's possible that there are problems with the beta version; we haven't used or tested the beta version extensively but it appears to work. When this becomes official, we'll update Wallaby to use this version.
