Error: did not recognize object of type "AssignmentPattern"

[extesy]

@1egoman I get this error while running debundle on a webpack (non-minified) bundle:

.....
* No lookup tabie for module 510, so using identifier as require path...
* 510 => 510
assert.js:42
  throw new errors.AssertionError({
  ^

Huh. Not sure what's going on there, but it looks like it's either a bug in escodegen or acorn (whichever one uses the module ast-types that's referenced in that stack trace). Also, is that the whole stack trace? It seems like there might be some lines missing from the bottom.

[extesy]

Yes, that's the whole stacktrace. I was able to fix that locally by bumping all dependency versions and updating cloned replacer module from using "traverse" to "visit".

[1egoman]

Closed due to inactivity

Hi, I have the same issue:

I have installed debundle globally as version 0.5.4 and I have node and npm version v8.11.3 and 5.6.0

@extesy could you explain to me how did you fix it?

[extesy]

@zauker update this package's package.json file to use latest dependency versions and then update its cloned replacer module from using "traverse" function to "visit".

[isbur]

@extesy Thanks! It worked out for me well too

Hi @extesy @isbur @1egoman could you please add a bit more instructions of how could yow resolve this issue? Many thanks
