vercel.json functions configuration not applied to created functions

[lalish99]

Summary

My account is currently subscribed to the Pro plan. So, according to the docs our functions should be able to have a max duration of up-to 300 seconds. But, I'm unable to configure the max duration or the memory of the functions of my deployment.

Here's my vercel.json file:

{
    "functions": {
        "pages/portals/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/topics/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/api/revalidate.ts": {
            "maxDuration": 30
        }
    }
}

The folder structure looks like this:

The deployment works as expected and I don't see any relevant errors on the build logs. But, after the deployment finishes, the properties of the functions are still the default values:

Am I misconfiguring something?

Steps to Reproduce

I'm not sure if this is replicable by others, but I have my vercel.json like this:

{
    "functions": {
        "pages/portals/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/topics/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/api/revalidate.ts": {
            "maxDuration": 30
        }
    }
}

Hey @lalish99. You can find some more info about configuring maxDuration at vercel.com/docs/functions/configuring-functions/duration#. When viewing the code examples, you can choose other frameworks and switch between typescript or javascript. Make sure you have the right options selected so you see the recommended method for your framework.

I need to know a bit more about your project to be able to give a specific solution. If you have a minimal reproducible example, that would let me see what framework and architecture is used.

@amyegan Our project is currently running on NextJS ^12.3.4, that's why I was using the Next.js versions older than 13.5 option described in the same docs you shared.

The problem is that the configuration isn't applied for any of the created functions. So, I was just wondering if vercel.json could get overwritten somehow? Or if there's why it could be ignored?

I've already read all of this discussion trying to troubleshoot. But honestly, I'm stuck. There are no clear errors on the logs, and the deployment works as expected. But as you can see, the functions still have the default configuration. The function shown in the following screenshot should have a max duration of 20 seconds, and a memory size of 2048 MB based on the vercel.json I previously shared.

{
    "functions": {
        "pages/portals/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/topics/**/*": {
            "maxDuration": 20,
            "memory": 2048
        },
        "pages/api/revalidate.ts": {
            "maxDuration": 30
        }
    }
}

No problem, I've asked my team to make the repo public.

The deployed function still has the default time-out value.

@amyegan where you able to replicate the problem?

[amyegan]

I was able to see the problem and I have a solution. Your project uses a /src directory, so you'll need to include that In the vercel.json config. For example, if you change "pages/api/revalidate.ts" to "src/pages/api/revalidate.ts" you'll see the expected maximum execution duration reflected on a new deployment.
