I am having some trouble using PlatformIO to upload files to SPIFFS.
I’m using a WeMos D1 Lite V3 as a web server serving static HTML files, but am unable to upload the built SPIFFS image to the board. I have placed my files inside the data folder (which lives on the same directory level as the src folder) and have tried to run pio run --target uploadfs with the following log output:
PLATFORM: Espressif 8266 > WeMos D1 mini Lite
SYSTEM: ESP8266 80MHz 80KB RAM (1MB Flash)

I am able to upload built .cpp files and run code on the WeMos successfully, but for some reason, file uploads fail. Any help would be greatly appreciated!
