Hi,
Can you please let me know if you are the Developer of the application or you are having the application and you are just writing over some test scripts for that? The purpose of this question is that I would like to know if you have access to the code or not.
This issue needs to be resolved from the Development side. While building any project that uses Syncfusion Essential Studio assemblies, they need to include a file called licenses.licx. This file will be embedded in to the exe in the name of ${application_name}.exe.licenses with Syncfusion licensing details included in that.
Please refer to the following article on how to solve this issue. If you are having access to the code, you can try this. Please let me know if this helps.
