[pejalo]

I can't wait to use Hosting + Functions integration! 😃

...
"hosting": {
    "public": "dist",
    "rewrites": [
      { "source": "/v", "function": "v" }
    ],
...

CLI:
$ firebase deploy --only hosting

i  deploying hosting
i  hosting: preparing dist directory for upload...
✔  hosting: 36 files uploaded successfully
i  starting release process (may take several minutes)...

Error: HTTP Error: 500, An unknown error occurred. Please contact support.

I'm curious -- if you make the "source" slightly longer, e.g. "/vee" does
it work? Might be a spurious server-side validation error.

@mbleigh Thanks for the quick response! Great idea. Turns out that the source is ok. It was the function name that was too short. This is great because of course the source is user-facing and the function name doesn't matter.

[laurenzlong]

Hey @pejalo so does this solve your problem? Can you close this issue if it does? Thanks!

[pejalo]

@laurenzlong Yes thanks, this worked for me. I still think functions names of a single character should be supported. But it's not a big deal, and at least this issue is here for reference.

[mihalik]

I know this issue is closed but I just ran into this and it caused a bit of frustration for a while. This issue is good for people that search Google but it would be nice if there was a more general fix. Is there a plan to fix the underlying issue, provide a better error message, or at least update the documentation to state that functions need to be longer than a single character?

[SamMatthewsIsACommonName]

For the record I also encountered this issue because of my own user error. I had a module import incorrenctly (e.g const {MY_FUNCTION} = require(....) vs const MY_FUNCTION = require(...) )
maybe this helps someone else who has the same problem :)
