I have not seen this one before. I will have time tomorrow to try this out and I will let you know.

@jeffwhelpley this error still persists

[brexis]

Any idea on how to solve this?

[jeffwhelpley]

Apologies. This is a solvable issue. I just haven't had time to dive in. Since there are now at least 3 people running into this, I will bump up the priority on my list and get to it later this week.

@jeffwhelpley thank you

[jeffwhelpley]

hey, are you guys using ts-loader? what version of TypeScript? I started working on this today and will be publishing a new version of Preboot later tonight, but I could not recreate the error. It may be because this only affects certain versions of TypeScript:

TypeStrong/ts-loader#278

[CaerusKaru]

Versions:

├── ts-loader@2.3.7 
└── typescript@2.5.3 

[jeffwhelpley]

I am pushing out another version shortly, but I noticed that a fix to this is to very simply change this line in your webpack.server.config.js:

resolve: { extensions: [".ts", ".js"] },

to this:

resolve: { extensions: [".js", ".ts"] },

I am still testing now, though, and will post any additional fixes.

[jeffwhelpley]

OK, I just published new version 5.1.4 but I believe you do need to make the fix I mention above as well.

For me this issue is still happening.
