Maximum call stack size exceeded issue

[websitesecurityguy]

I am using tsec to catch trusted type violations within my project. When I use it to analyze 3p generated ts files, like files from babylon, I get a "Maximum call stack size exceeded". After playing around with it, I noticed this happens for versions of typescript greater than 4.5. If I downgrade to less typescript versions than 4.5, tsec can complete the run and display any TT violations. Is this something that has been seen before? Are there recommendations on what versions the dependencies for tsec should run on?

I haven't seen this error before. Maybe because I have never run it on very big TS files. Could you share a reproducer?

Unfortunately, I don't think tsec is used very much in the OSS community. I'm working on a new tool for surfacing Trusted Types violations (https://github.com/google/safety-web), which is an ESLint plugin. You may try installing it and see if it works for you, but it's still under development. I made a release at https://www.npmjs.com/package/eslint-plugin-safety-web.
