Unable to increase memory limit on Serverless Function

[Ryanjso]

Question

Hello, can anyone help me figure out why my Serverless Functions aren't deploying with more memory. I have tried setting it in both vercel.json and export config in the api itself. Neither seem to change what is shown on the function page. It's possible it does have more memory but the page itself is incorrectly showing 1024, I'm not quite sure how I would check that. For context I am on the Vercel Pro Trial so should have access to more memory.

I'm experiencing the same thing

Hey I eventually figured out the issue, I have my app inside an src folder so I needed to add that to the key like so:

    "src/pages/api/instance/sync.ts": {
      "maxDuration": 120
    }

The issue is if you write a function path that doesn't exist like "pages/api/doesntexist.ts" Vercel will throw an error that the function doesn't exist, but in my case the function did exist, my path just didn't go correctly to it so Vercel didn't throw any errors. It seems Vercel's code that checks if the path exists has different rules than their code that actually handles the configuration changes, so it was silently failing.

Hope this helps :)
