React-Native-FS ANY filepath gives me "ENOENT: no such file or directory"

Question

Any value I put in for firmwareFilePath gives me "ENOENT: no such file or directory".

const firmwareFilePath = "./assets/BLE_chef.bin";
const firmwareData = RNFS.readFile(firmwareFilePath, 'base64');

Even RNFS.exists gives me a false. I'm trying to run this on ios device, how do i get it to actually find the files?
