Hi, since yesterday I suddenly got below error on ‘storeHtmlSource’ and ‘storeText’ command in a Test Case which was working fine before.
Then I see that in happens to the Sample projects, offered by KR as well.
I see two old post with the same issue here but there isn’t any proper answer or solution for them
I’ve also tried it two different machines and get the same result.
Does anyone else face the same issue?
[error] Cannot read properties of undefined (reading ‘getCommandHandler’)
The issue was a js file in my scripts. Although I was not using that, it was causing error!
Hi,
Let me investigate nd bck to you
Today I started to getting that error on steps that include ‘waitForElementPresent’ on a working Test Case. I’m using Katalon Recoder v5.9.0 in Win/Chrome. I uninstalled the extension and re-installed but no luck. I also tried using the Edge (v5.8.3) browser but same error.
Other steps like click and type work fine. Any idea what’s up?
Issue Solved!
Turns out I had inadvertently put a Test Data CSV file into the Extension Scripts folder.
I tried deleting the errant CSV file but that was not sufficient.
I tried deleting the file then making a backup and restoring but, the errant CSV file would again be in the Extension Scripts folder.
When I manually removed the Extensions section out of the JSON restore file, then Restored, everything went back to normal. 
Ran into this issue today. Been working on a few new custom commands recently, and had been trying to debug the most recent one (there’s a caching issue Katalon Recorder has around this, but that’s its own issue), but had put it on hold, till I came back to it today.
When I attempted to execute any of my custom commands, all of a sudden ran into this error. Restarting Katalon Recorder (7.1.0, macOS, Chrome v129) made no difference, neither did restarting the browser, removing all Extension files and restarting, etc.
Considering doing a manual extraction of the Extensions data as described above, but a bug fix for this issue would be even better! (@vu.tran / @Elly_Tran)
