2020.10 Upgrade Error - Method 'GetServiceUrl' not found in interface. 'UiPath.Service.Api.SettingsOperations

[botman]

I successfully upgraded our on premise orchestrator from 2020.4 to 2020.10 and I am getting the below errors after installing the 2020.10 studio/assistant and attempting to connect the studio/assistant/orchestrator. Any solutions?

“Method ‘GetServiceUrl’ not found in interface. ‘UiPath.Service.Api.SettingsOperations’”

Hope this helps you

I restarted the system and I’m still getting the error. I tried it on a different server and getting the same thing over there as well.

I also tried connecting to orchestrator via studio and when it prompts me for the URL and machine key I provide it, then get error saying ‘Value cannot be null. Parameter name: source’.

Value cannot be null. Parameter name: source’.

@botman

Can you share your UiPath Assistant->Orchestrator Settings screenshot

Also check any Firewalls / Antivirus is blocking your connection

Hope this may helps you
Thanks

@Srini84 The assistant is saying I’m licensed and connected after I click OK on this pop up. However I can’t access Studio without getting the ‘Value cannot be null’ error.

Azure App Orchestrator Url

Hi all, I installed an Azure Orchestrator App for my client, and now they want me to customize their Url to something like “www.companyname_orchestrator.com”. is this possible? if yes, please guide me through the process. the current URL address is something like: https://uipathorchestrator-mkrtfn4ywq2vm2ewhhdjs.azurewebsites.net/account/login?returnUrl=%2F

Hope this helps you

Thanks

I heard back from support and they were able to provide me a solution. Essentially I had two different versions of Studio installed on the server and that’s what caused it. I installed the .exe and should’ve installed the .msi.

Steps :

• Open Start Menu

• Search for Add or Remove Programs

• In the Search box, search for Studio.

• If you find more than one UiPath Studio, then kindly uninstall both the studios. (Do a backup of Projects/Packages)

• Click - UiPathStudio.msi and install Studio in Service mode.

• Follow steps in the Manually Connecting Robots section from the link - https://docs.uipath.com/orchestrator/docs/connecting-robots-to-orchestrator#manually-connecting-robots [docs.uipath.com]
