Restarting Not Working for TypeMismatch Error


#1

All I did was drag the Activity - Open Browser - and set it to google.
I have tried restarting UIPath multiple times but am still getting the error below.

19.1.0+Branch.master.Sha.3db2bfe8751ed76c2c21f7ee16f53ff69a3e3b75

The message with Action ‘http://tempuri.org/IUiPathRemoteDuplexContract/SubscribeToEvents’ cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

System.ServiceModel.ActionNotSupportedException: The message with Action ‘http://tempuri.org/IUiPathRemoteDuplexContract/SubscribeToEvents’ cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher.

@DocM - Did you recently update UiPath? Try restarting your machine and check if it helps!


#3

If this doesn’t work, please reinstall the newest version of Studio.


#4

I just downloaded it, it’s my first time using it.

OK, uninstalling and then reinstalling worked! Thanks a bunch!
