Theres an issue with this plugin.

3

Is this any known issue ??
How to point it out ? Can you please elaborate ?

4

Since you ported over your project, more than likely something broke. In this case it would be the file plugin you are using. I would suggest to remove the plugin and add it again to see if this fixes the error.

Actually i have 3 plugins package.json

    "@ionic-native/file": "^5.30.0",
    "@ionic-native/file-opener": "^5.27.0",
    "@ionic-native/file-transfer": "^5.30.0",

Do you know which one should be problem ? Meanwhile I will try removing all of them and re add them.

Also what is the correct way to remove plugin.

npm uninstall file

is this correct way ?
