Ionic native File-Transfer

Hi, I have a problem. I want to send a picture to a remote api and I’m using the cordova native File-Transfert plugin. When I send the picture I always get the error code 1 (file not found) and I don’t understand why. I look for the file manually and it exists.

cordova-plugin-file version: 5.0.0
cordova-plugin-media-capture: 2.0.0
cordova-plugin-file-transfer: 1.7.0
Android platform version: 6.3.0
Ionic version: 3.19.0
Cordova version: 8.0.0

Does code 1 really mean this or is this just a response from your API you are sending the data to?

Thanks for the replay. Following the original documentation of the plugin code 1 mean file not found. Isn’t a response from the api but is a error from the library.
