SPIFFS_write error(-10010): unknown

[vyruz1986]

Thanks so much for releasing this tool, I was waiting on this to continue work on my project (FlyballETS)

I have made an angular v5 web app using Angular-CLI which needs to go on the SPIFFS filesystem. The angular-cli build generates the necessary files for production use. I have uploaded a data.zip file containing the output of this production build: Link

When I put the contents of this zip file in a /data/ folder of my arduino sketch and run the ESP32 Sketch Data Upload, I get the following error:

[SPIFFS] data   : C:\Users\alexg\OneDrive\Projects\FlyballETS-Software\data
[SPIFFS] start  : 2691072
[SPIFFS] size   : 1468

SPIFFS_write error(-10010): unknown
error adding file!
SPIFFS Create Failed!

I did some testing and it seems the file name length is the problem, I tried just uploading one file from the package and then started renaming it using trial and error:

NOK	: inline.a44fd682ff3096930d6e.bundle.js

OK	: inline.a44fd68236933.bundle.js
NOK	: inline.a44fd682369333.bundle.js

The 3rd line is 30 characters, 4th line is 31 chars.

Yup :) SPIFFS file names can be 32 bytes max (including starting slash and zero at the end). This is a known limitation :)

Thanks for clarifying. Better return error from the tool would be a nice improvement though 🙂
