[Bug?]: ERROR Function "" was not found. about redwood

[simoncrypta]

Out of curiosity, are you hosting on render.com as well, or another service?

Yes, we are on render.com.

I did some tests, and you're right about this getting on every server start. I inspected the RW code and nothing seems to trigger this. Not only that, but I also didn't experience this with build/serve locally. I'm pretty sure that it's triggered by render.com as part of the graceful start.

Thanks, @Tobbe! There's no problem with assigning this low priority. At least it's logged, and if anyone else sees the issue, they have a place to add their info as well.

It's usually bots that try to crawl the API url.

I also saw a lot of:
ERROR Function "wp-admin" was not found.
And
ERROR Function ".env" was not found.
That's definitely bots that try to execute commons WordPress vulnerability.

I don't think anything needs to be done except maybe return a more accurate HTTP code and perhaps not log this as an error?

Thanks for the quick response @simoncrypta !

I am, however, only seeing this error upon a deploy and server start... consistently. Thus, I don't believe it would be a bot. Maybe there's a unique render.com thing that happens? Thanks!

Thanks for the issue report Curtis 🙏 I don't have any good guesses on what could be causing this right now. And seeing as this isn't a critical issue unfortunately we're going to have to give this one a pretty low priority for now.

Maybe the health check path points to the root ?
You can check this on the setting tab of your api service.

I also recommended using the built-in health path from GraphQL, so that way you don't only check if your server can respond, but also check if GraphQL can respond correctly.

@cjreimer Actually, maybe you're right, we get between 10 and 100 Function "" was not found by day, but I can't find any pattern that could be caused by render, RW, or even our users. It could be plenty of bots, but I'm not sure how common it's.

We are at V6.0.7 with RW

[cjreimer]

Interesting!

I hadn't noticed it before V7 of RW... but we hadn't updated the server for a while before this. I believe we were sitting at RW v6.6.1 before this upgrade yesterday. Note that as of yet (~1 day), our experience is that we only get these errors on a server start.

Interesting idea to change the health to the graphQL health function... we may need to look into that. The health function we have is getting hit every 5 seconds or so by render.com, so as of right now we've kept it as lightweight as possible.
