Javascript error from selecting a dropdown item

[Hamza]

Hello all,

I am getting a JS error when the test select a value from a dropdown list. The change triggers a JS call.
I am getting an error when that happens (error below).

Any help will be much appreciated!

Thank in advance.

 

ExecuteCommand failed!

InError set by the client. Client Error:

Hi Hamza,

What version of Test Studio do you use?

Could you please try adding a WaitForExists step for that drop down list.

If the issue persists is there a possibility to grant us a direct access to your application so we can reproduce this.

Hope to hear from you soon.

Hi, 

I don't know what your problem exactly. However, while working on dropdown lists, using index property of dd lists is better than value property. You can try your test with index property of dropdown list.
