Accessing non-existent property 'then' of module exports inside circular dependency

[shunguoy]

this only happens with a large page, and if some of the items are removed from the page, it works just fine.
The key issue is following:
Warning: Accessing non-existent property 'then' of module exports inside circular dependency
at emitCircularRequireWarning (node:internal/modules/cjs/loader:834:11)
at Object.get (node:internal/modules/cjs/loader:850:5)
at
at step (git/equal-access/accessibility-checker/src/lib/common/config/ACConfigManager.js:7:47)

seems there are circular dependencies among modules, and a promise-like object is used before it's fully initialized. but don't know exactly which one.
