Product Forums Katalon Studio
,
1

I am not being able to start either an iOS application nor an Android application on Kobiton devices using Kataon Studio’s latest beta version 6.3.0.

Steps to reproduce:

  1. Create the KS test script using a physical device
  2. Created a trial account on Kobiton
  3. Uploaded .apk/.ipa file on Kobiton Apps
  4. Made a few devices as Favourite on Kobiton
  5. Carried out the rest of the steps as instructed here: https://docs.katalon.com/katalon-studio/docs/integrate_with_kobiton.html#mobile-testing-with-kobiton-devices

Observed the following error on the execution log:
SLF4J: The requested version 1.7.16 by your slf4j binding is not compatible with [1.6]
SLF4J: See SLF4J Error Codes for further details.

Hi @Noor_Yeaser_Khan,

@duyluong - Hello! Thanks for coming once again to save me. I did clicked on the Kobiton Device after pressing the down arrow on the Run button. Unfortunately, I am still getting the same output.

Additional info:
Upon Spying/recording, I’m getting the following error message:

Hi @Noor_Yeaser_Khan

If you use the beta version, please update to KS v6.3.2 release. Your issue only occurs in v6.3.0 beta version.

Thanks

@duyluong - Thank you so very much. I highly appreciate your prompt responses. Updating from v6.3.0 to 6.3.1 resolved my issue. Now I’m not seeing that error any more. Thank you so much! :bowing_man:
