Did you follow polyfills doc page instructions?

[SkyleOri]

I tried to import it into all the files which are using @pnp, but it still did not work, the same error still show. Please let me know if I missed something.

Are you running this in SPFx and what if so what version? Also, did you enable ie11 mode?

[SkyleOri]

No, I do not use SPFx.
About enabling ie11 mode, I missed it, but it seems not to work after I add it.

Might help https://github.com/pnp/pnpjs/issues/1002#issuecomment-572975881

You will need to make some modifications for use outside of SPFx solutions.

Was able to reproduce this - unsure why we didn't catch it. I have added the sumbol polyfill to the polyfill package. Just published a new polyfill package 2.0.1 - give that a try and things should now work.

Going to close this as resolved with the new version of the polyfill library. If someone has further issues please open a new issue and ref this one with the new details. Thanks!
