when we are using fastboard and installing it in repo then this new error is coming
Uncaught TypeError: Cannot set properties of undefined (setting 'type') at push../node_modules/mathjs/lib/esm/type/fraction/Fraction.js.Object.isClass
This is probably a bundler's config issue. More details see: https://github.com/josdejong/mathjs/issues/3022
I can't help much in these kinds of issues as I don't know webpack very much too.
In case you do not use the legacy PPT function in white-web-sdk (new customers should prefer using the "projector" conversion service), you can invalidate the mathjs package in your dependencies tree to avoid this issue. I have published a new package to help doing this:

Please refer to its README to solve the issue.
