Hi @ti.wang01, @qatools

Please update to v7.7.2 for the fix.

In fact, this issue is still reproducing on v7.7.2:

thank you. i will try and soon to report it again

Glad to hear that, @Alwan_Firdaus. If the problem still persists, please share with us your whole project, via private messages, for further investigation.

sorry @huynguyen

this version just application of katalon? how if i want to update on docker image? because my problem when running on jenkins with docker image

this is my sample

Hi @Alwan_Firdaus,
We haven’t built the Docker image for this version, as it is still the release candidate. To have the fix available in the official release, I need to be confirmed that the fix actually works when you use the standalone KRE.

hallo @huynguyen

if i try in running in local with GUI, not from jenkins, the log is
