@polkadot/api 7.11.1 not working with jest testing framework

[akileshtangella]

I am getting the following error:
Must use import to load ES Module: [...]/node_modules/@polkadot/x-bigint/shim.js. Any insights on how to solve this would be appreciated. I tried configuring my jest config file and tsconfig.json in multiple ways, but nothing seems to work.

There are multiple issues on Jest, see https://github.com/polkadot-js/api/issues?q=is%3Aissue+is%3Aclosed+jest

The bottom-line is that Jest ESM support seems to be lagging behind and it pulls in ESM despite the export maps. Most of the above issues have workarounds/configurations.

EDIT: It seems the upstream Jest issue for export map support is closed (just in time for the Node 12 deprecation where it was first added) and they seem to support it in Jest 28 (only alpha for now) from my reading of jestjs/jest#9771
