Crash loading examples

[ktiedt]

I've tried several of the examples and they all seem to crash and reboot... I've tried with and without config.json files, empty file, just an empty json object... all result in the same failure.

Rebooting...

Hi @ktiedt

The problem is due to the wrong size of /setup/config.json file. I assume you have tried the simpleServer.ino example which unfortunately due to a bug creates an invalid configuration file.

Do an "erase flash" to delete it and try one of the examples that provides custom options (e.g. customOptions.ino) Or simply add a "pretend option", for example with statement called before begin()

myWebServer.addOptionBox("Test");

This way the file is created correctly. In the meantime I will fix this bug for the next release.

I had a similar problem on my ESP32-S3. In my case the corruption the WiFi stored parameter (I guess ). I have tried to load with flash erase but it did not work.
I ended up using a simple program with ssid and password for my WiFi. This time the S3 came back. I can not explained what happened , even debug prints in setup() were not executed !
