I am getting the below error while trying to click on a  element in the application.
at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse) in c:\Projects\webdriver\dotnet\src\webdriver\Remote\RemoteWebDriver.cs:line 1167
   at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) in c:\Projects\webdriver\dotnet\src\webdriver\Remote\RemoteWebDriver.cs:line 920
   at OpenQA.Selenium.Remote.RemoteWebElement.Click() in c:\Projects\webdriver\dotnet\src\webdriver\Remote\RemoteWebElement.cs:line 339

Below is the code:
Dim oNextHI As Object = WaitForElement(driver, WaitForTime, By.XPath(".//*[@id='pageTemplateForm']/div[2]/table/tbody/tr/td[2]/a"))
            If Not oNextHI Is Nothing Then
                nextImpSSEle = DirectCast(oNextHI, IWebElement)
                nextImpSSEle.Click()
