Unable to wait for object to be clickable

Hey Community i tried to fix the issue of unable to click on object , so i tried waitForElementClickable and it worked then for the seconde line i tried also waitForElementClickable but does not workand told me com.kms.katalon.core.exception.StepFailedException: Unable to wait for object to be clickable
at com.kms.katalon.core.webui.keyword.internal.WebUIKeywordMain.stepFailed(WebUIKeywordMain.groovy:64)

This sentence implies to me that you have 2 consecutive lines which are exactly the same, and the 1st line passed and the 2nd line failed; like

WebUI.waitForElementClickable(findTestObject("some/name", 10)   // passed
WebUI.waitForElementClickable(findTestObject("some/name", 10)   // failed

Is it what you did? If not, please describe your issue more precisely.
