Iframe issue on katalon

Hi @anishas,
Remove the 5 second Delay.
Change the ‘Switch To Frame - frame_Contribution Receivables’ to 30 seconds or more.
Remove the second ‘Switch To Frame - frame’
Retry the test.

Alternatively this might help…
Create your self a new test object
Right click on Object Repository > New > Test Object
Create ‘testIframe’ for example

Click on the ‘Xpath’ tab and set the value to //iframe or (//iframe)[1] or (//iframe)[2] if you have 2 iframes, save the object.

Add the following to the test case body:

// Switches to iframe
WebUI.switchToFrame(findTestObject('Object Repository/testIframe'), 90)
// Your code ...
// Switches from iframe
WebUI.switchToDefaultContent()
