Hello! I'm trying to add my instagram's feed to my page according to your code on this repository , but an error occurred with the .mp4 format files of the videos I have:

"warn You can't use childImageSharp together with 10603_34563580515_n.mp4 — use publicURL instead. The childImageSharp portion of the query in this file will return null"

And it doesn't work neither for the images on .jpg format.

Any ideas? I appreciate the help :)

Avoid hardcoding values that are meant to be secret. Found a hardcoded access_token in gatsby-config.js.
Gatsby environment-variables

The problem is that other developers copy your code and do the same mistake instead of getting used to use secrets ;-)
