Hi there, seems like there is an error in the first highlighted line of index.html (pg 133). I had to change firebaseConfig to config and then it worked. The naming seems to be inconsistent
As usual the problem is in front of the monitor – I missed copying the last two lines – my fault.
Nice project, worked out of the box and I learned a lot.
In fact, there is an error in the PDF. We already added that to the ebook ERRATA:https://rntlab.com/module-1/firebase-web-app-with-esp32-and-esp8266/
The code that you download from our resources is correct. I already checked that out.
Did you follow the project until the end? What did you think?
