Hi @Aliaksei-Ashukha

Please find my below logs , at the time of healing getting null pointer exception from Healenium -

@ashish143ti: can you give your code as i have created a maven project ,while iam running iam getting nosuch method error typeConfig issue

ashish143ti commented 3 years ago

Hi @Mitrabhanu-tech ,

I didn't get such issue at the time of Appium integration , I guess you are getting this issue due to type safe (jar) version conflict issue or instead of using healenium appium 1.2 maven dependancy you have directly imported healenium appium jar in to your project, kindly use maven dependancy of healenium appium 1.2 , in case you are already using healenium appium dependancy than remove existing type safe config maven dependency or declare below dependency in pom.xml .

com.typesafe config 1.4.1

@Mitrabhanu-tech - I have tested this solution closely and found self healing not working , hoping Healenium team will fix this major bug in upcoming days .
