I'm not entirely sure how to interpret testapi output, but looks like there is more that one failure: callback should receive rejected promise as first argument: FAILED callback should receive rejection reason as second argument: FAILED callback should not receive a third argument: PASSED C-API tests in C++ had 2 failures ASSERTION FAILED: !testCAPIViaCpp(filter) /Volumes/Data/worker/Apple-Monterey-Debug-Build/build/Source/JavaScriptCore/API/tests/testapi.c(1409) : int main(int, char **) 1 0x112cb4ab0 WTFCrash 2 0x100823f80 main 3 0x100ced088

I've also seen this fail intermittently on a Release build on M1 (when testapi is run while some heavy load is running in the background like a WebKit build). I've never seen it on a Debug build yet.
