Hi @Ssb_94, error says task list you have referred in the campaign
workflow does not exist in the instance you are trying to perform
import.You need to import task list first and then the campaign.Try to
import just the task list. Make sure task list with value 'abcTSK4376,
abcTSK4378, abcTSK4387, abcTSK4385, abcTSK4382, abcTSK4377, abcTSK4379,
abcTSK4380, abcTSK4384, abcTSK4381, abcTSK4386, abcTSK4383, abcTSK4388,
abcTSK4375' exists in the instance and then perform campaign import.
Thanks,Jyoti
