Github action cronjob curl POST doesn't always work

Question

I've setup a github action on a private repository, free account, as a cron so that runs every day at 9am:

name: updates
on:
  schedule:
    - cron: '0 9 * * *'
jobs:
  cron:
    runs-on: ubuntu-latest
    steps:
      - name: Call our API route
        run: |
          curl --request POST \
          --url 'https://mysite.vercel.app/api/myjsfile' \
          --header 'Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}'

but I've noticed that while if I open https://mysite.vercel.app/api/myjsfile manually in browser it works as expected, saving all the data in my mongodb (inside myjsfile.js it goes through a for loop and save each in a collection), when it gets called via cron either it doesn't work or it goes through 1-2 loops at max.

What am I doing wrong here? I've checked for github action timeouts but it seems the cron timeouts after hours, so it shouldn't be the issue here since the whole process when I open the api url manually it takes about 3-4 minutes

EDIT 1: modified to GET request as suggested, but without any changes

EDIT 2: thanks to the logging suggested below, which returns:

I've seen that there's a NO_RESPONSE_FROM_FUNCTION error at the end, and it may have to do with the fact that the plan on vercel is a "hobby" one for now, so it may be the max timeout of 10s for serverless functions as shown in the screenshot below?

It's weird though cause when I go to the /api/myjsfile manually as said it works fine, is it because isn't seen as "serverless" by vercell contrary to when it's executed via cronjob?
