Im creating my first homey app for personal use that uploads a file to s3 bucket. when runnning my app by `homey app run` the flow card works as expected but when using it through `homey app install` im getting this error:

```auto
A system error occurred: uv_os_homedir returned EEXIST (file already exists)

```

for anyone googling this i solved it by adding

```
  process.env.HOME = '/tmp';

```

apparently s3client is looking for a home folder but homey doesn’t have one. by setting a fake one this problem is circumvented.
