ReferenceError: unknown node of type "Literal" with constructor "Object"

[edmorley]

Hi!

A user of Neutrino reported an issue with their project when they updated their dependencies (mozilla-neutrino/neutrino-dev#984) that upon creating a reduced testcase, appears to be due to fast-async / nodent-compiler regression.

The exception no longer occurs if nodent-compiler is rolled back to v3.1.8 (eg using yarn's resolutions feature). The first version of nodent-compiler that triggers the exception is v3.2.0.

STR:

1. Clone https://github.com/edmorley/testcase-fast-async-unknown-node
2. yarn
3. yarn babel testcase.js

Expected:

Command completes successfully, or else if the testcase's syntax is invalid, a helpful error message is output.

Actual:

ReferenceError: testcase.js: unknown node of type "Literal" with constructor "Object"

Thanks for reporting this. It's now fixed in nodent-compiler@3.2.9.

Please re-open if this doesn't resolve your case.

This issue no longer reproduces with the new version. Thank you for the fix :-)
