Cannot save my API request - getting "WebElementXpathEntity declares multiple JSON fields named name" error


#1

Hi everyone,

I’m new to Katalon Studios, and I am trying to save my first draft API request to the Object Repository in a new project, and it is throwing the following error message.

I’m on Katalon Studio version 6.1.5

Does anyone have any ideas on how to fix ?
Thanks in advance
Kind Regards
Ian
