React-native-fs: Error with downloadFile

[tlloydukdev]

Hi,

I'm trying to do a simple downloadFile operation with react-native-fs on iOS simulator, e.g.

import fs from 'react-native-fs';
fs.downloadFile({
            fromUrl: 'http://www.domain.com/database.db',
            toFile: fs.DocumentDirectoryPath + '/database.db'
        })
        .promise.then((res) => {
            fs.exists('database.db').then((exists) => {
                // File was downloaded
            });

        })
        .catch((error) => {            
            console.log(error);
        });

I've tried with and without specifying DocumentDirectoryPath, however the catch always fires, and error contains:

ReferenceError: e is not defined
at FS.common.js:487
at tryCallOne (core.js:37)
at core.js:123
at JSTimers.js:301
at _callTimer (JSTimers.js:154)
at _callImmediatesPass (JSTimers.js:202)
at Object.callImmediates (JSTimers.js:470)
at MessageQueue.__callImmediates (MessageQueue.js:329)
at MessageQueue.js:147
at MessageQueue.__guardSafe (MessageQueue.js:316)

If I click FS.common.js it shows this block of code

.catch(() => {
        return Promise.reject(e);
      })

I have added my domain to App Transport Security in case it was that, I don't have any build errors, the 'exists' method seems to work fine.

"react": "16.2.0",
"react-native": "0.52.2"
"react-native-fs": "^2.9.9"

Installed fs using Podfile all OK.

Any thoughts ? Feels like I'm missing something obvious

seems editing FS.common.js and changing it to .catch((e) fixed it which then led to an error about App Transport Security, so I know what to fix now. Looks like a small glitch that needs fixing

I am facing the same problem. Did you fixed it ?

[yasoza]

it worked. thank you very much. I wonder how do you people find these solutions.

Thanks for reporting the issue! I fixed the catch-handler and just published 2.9.10!
