Cannot bind to the target method because its signature is not compatible with that of the delegate type

Hi I encounter this error just today. It has been running fine all these while. Today i could not debug nor run file.

Any advice and solution on this?

  • What is your Studio version?

  • Which are your project dependencies and their versions?

  • How you build the project?

  • For which activity you receive that error?

  • The error is reproducible in new projects with the same dependencies?

  • Which are the results for the impacted process if you are doing the below:

    • Close the Studio project.
    • Edit the project json and remove the “UiPath.System.Activities” dependency
    • Open the project in Studio and re-add the “UiPath.System.Activities” dependency
