Oops, the compiler has encountered an unexpected situation.
This is a bug in the compiler.

A bug report containing the error description and relevant code would be
greatly appreciated. You can submit the bug report here:

error: failed to run test for target Js

Caused by:
    failed when testing

Also, if you have any ideas about mocking @console here, please let me know... I'm still trying to figure out how best to do this for local unit testing.

Ah... maybe I can use different files for @console:

• console_wasm.mbt
• console_js.mbt
• or maybe console_js_test.mbt

This seems to be caused by usage of inline wasm code when compiling targeting Js backend. Can you check it? We will try to improve the error message for such cases.

Ah, yes, that must be it. Thank you, @Yu-zh !
