Sylph throws exception when fetching aws devices. about sylph

[mmcc007]

A device is of the form:

      - name: Apple iPhone11
        model: iPhone11
        os: 13.1.3

not

      - arn: arn:aws:devicefarm:us-west-2::device:58D6FB12B3624256AED26D0F940D4427

For example, to find available android Pixel devices:

sylph -d android | grep Pixel
name:Google Pixel, model:Pixel, os:7.1.2, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 2, model:Google Pixel 2, os:8.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 2, model:Google Pixel 2, os:8.1.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 2, model:Google Pixel 2, os:9.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 2 XL, model:Google Pixel 2 XL, os:8.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 2 XL, model:Google Pixel 2 XL, os:9.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 3, model:Pixel 3, os:9.0.0, deviceType:android, formFactor:phone, availability:BUSY
name:Google Pixel 3, model:Pixel 3, os:10.0.0, deviceType:android, formFactor:phone, availability:AVAILABLE
name:Google Pixel 3 XL, model:Pixel 3 XL, os:9.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 3 XL, model:Pixel 3 XL, os:10.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 4 (Unlocked), model:{GA01188-US}, os:10.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel 4 XL (Unlocked), model:{GA01182-US}, os:10.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE
name:Google Pixel XL, model:Pixel XL, os:8.0.0, deviceType:android, formFactor:phone, availability:HIGHLY_AVAILABLE

Select the Pixel devices you want to run tests on by name, model, and os and add to an android pool.

@mmcc007 I have tried this form as well :

name: Google Pixel 2
    model: Google Pixel 2
    platform: ANDROID
    os: 9

Have got the same exception.

This command doesn't work for me as well : sylph -d android | grep Pixel

sylph -d android | grep Pixel
Unhandled exception:

Confirm that your aws command is configured to return json by default
eg,

cat ~/.aws/config
[default]
output = json
region = us-west-2

(https://github.com/mmcc007/sylph#aws-cli-credentials)

A command such as aws devicefarm list-devices should return valid json.

@mmcc007 thanks you for your help, it was configured to return table. Have change it to json, but now i'm running into another issue. Maybe you can give me some advice?

The exception I'm running into is the following:

@AnzhelaAninian Looks like the code to handle local packages (needed when local packages are present) expects the path to tmp directory to be absolute:

tmp_dir: ./tmp/sylph

should be

tmp_dir: /tmp/sylph

(I've opened an issue to remove tmp_dir from config file... and another one to remove dependency on aws to be configged for json. Thanks for your feedback!)
