Crash on page load

[mano1979]

On a generic ESP32-dev board:

Uploaded the filesystem with the sketch. first time i didn't do a reset. I just let it run after upload. Not every file was written so i got the "Control Offline" message.
2nd upload and a reset after the upload fixed this.

But now when i load the page, i get nothing and the esp32 reboots. serial output below:

hey, sry for the late response, what version of the espasyncwebserver library are you using? I am going to test this in the next days again

[mano1979]

That has to be the latest version. I downloaded it all 2 days ago.

OK then, this issue drove me crazy today.... The problem is that the prepareFilesystem function does write the files correct, and if I list the filesystem contents immediatly afterwards it looks all fine

But when I list the contents in a new sketch it only shows some of them.... and if the webserver can not find them it crashes

This stops once I remove all file exists and remove operations in the function. I am not sure why this is but for now I'll leave it like this, if anyone has an Idea why the FS on the ESP32 behaves so strange please let me know

I released a new patch version with the delete parts commented out

[mano1979]

I tested the patch, but i still get the "Control Offline" page.

This is an annoying problem, I have to do more checks but for now pls use the ESP32 Sketch Data upload tool

As you can see in your debug output there is always one file with a size of 0, in this case /js/controls.js...
This somehow causes the server to crash...

[mano1979]

indeed. uploading using the sketch data upload tool worked.

[mano1979]

Do you happen to know if it is possible to give the sliders "touch" support?
Now you have to tap somewhere on the line, hoping you land in the right spot.
If the sliders where drag-able, then we can see the number according to position.

Any help or clues on where to start are appreciated. :)

[s00500]

Hm, that actually should already work... If it doesn't: can you put it into a new issue and put in info about the device you are using?

[cmorrow101]

I wanted to share an observation. I see the same reset problem when connecting through chrome web browser, however when I setup a hotspot on my phone, then connect to the ESP32(using the same phone) and mobile chrome, all works perfectly.
What is the difference when connecting directly vs through a network router?
Hopefully this is another clue. Great work BTW, love the interface.

[s00500]

This is probably some caching related issue you are having there, anyway the main problem is that the files are not written to the filesystem properly using prepareFilesystem() ...

[s00500]

Alright everyone: Great News: I retested on ESP32 and on ESP8266 and both are working fine with the newest versions of the arduino cores, this means this issue can be closed now =D
