Hi everyone,

I was following the nextjs tutorial and reached the stage of using prerendering for markdown files.

After following all the steps in the tutorial I got:

TypeError: Cannot read property 'map' of undefined

Has anyone managed to understand why this is happening?

The tutorial can be found here

I only found this git issue


Submitted a Github issue to Nextjs Team, the issue can be found here

The problem got fixed: I had a typo in _app.js Pros instead of Props

Thanks @kartikpandey2, for showing me where the problem was.

Thanks in advance
