I never had an issue in Katalon 6, but seems like when the URL contains a “|”, and I use the Rest Request from Objects, I get an error like this:
2020-02-16 11:20:15.869 ERROR c.k.k.core.keyword.internal.KeywordMain - Unable to send request (Root cause: java.lang.IllegalArgumentException: Illegal character in path at index 118:
My issue is different. I originally did not encode and for some reason, Katalon does not know how to automatically encode a “|” character. In my opinion, this is a bug because previously in 6 it accepted it and now it doesn’t accept that character at all and does not try to encode it either.
