In bug 1921095 I'm having to add a // eslint-disable-next-line import/no-unresolved exception in the test for our custom no-base-design-tokens. The eslint error seems to be stemming from the fact that the imports plugin doesn't currently recognize when "exports" is used instead of "main" in a packages package.json file - more info/context can be found in these bugs. Once this issue is resolved in the plugin/on the eslint side of things we should loop back and remove this exception as well as any other exceptions we've had to add to similar tests for custom rules.
