Environment

Based on the description provided, it seems that the issue is related to the Elsa.Activities.Rpa.Web package not being able to find or download the appropriate ChromeDriver version for Chrome versions equal to or above 115. This could be due to changes in the API used to fetch the ChromeDriver or changes in the versioning scheme used by the ChromeDriver project.

To resolve this issue, you may need to manually download the appropriate ChromeDriver version that matches your Chrome browser version and ensure it is available in the expected path for the Elsa.Activities.Rpa.Web activities to use. Alternatively, you can check if there is an update to the Elsa.Activities.Rpa.Web package that addresses this issue or if there is a workaround provided by the maintainers.

You should also report this issue to the maintainers of the Elsa Workflow project if it has not already been reported. They may provide a fix or a more suitable workaround.

For now, you can try the following steps:

  1. Visit the official ChromeDriver download page: https://sites.google.com/chromium.org/driver/
  2. Download the version of ChromeDriver that matches your version of Chrome.
  3. Place the downloaded ChromeDriver in a directory that is in the system's PATH or specify the path to the ChromeDriver when configuring the RPA activities in your workflow.

If you are unable to resolve the issue with these steps, please provide additional information such as the version of the Elsa.Activities.Rpa.Web package you are using and any relevant configuration details for the RPA activities in your workflow.
