Getting "Invoke-RestMethod : The remote server returned an error: (404) Not Found." when trying to call an end-point

PowerShell Universal
1

Hello,
Newb here, I just discovered Powershell Universal a few hours ago and I’m intrigued. I installed the software on my Windows 10 and testing here. I created a very simple script “get-process” just to test to see if I got any about from the PowerShell console.

I can run the script in the portal without any issues. But when i run it “remotely” local PowerShell console i get the following error message:

Invoke-RestMethod “http://localhost:5000/test”
Invoke-RestMethod : The remote server returned an error: (404) Not Found.
At line:1 char:1

  • Invoke-RestMethod “http://localhost:5000/test”
  •   + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
  + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

I followed the doc step by step. I’ve disabled the local firewall temporarily to get that out of the equation so i dont know what I’m doing wrong.

I appreciate your time/assistance and advise in advance.

Hi,

Could you please send the content from endpoints.ps1, it’s usually located in
cC\ProgramData\UniversalAutomation\Repository.universal

Hello,
Thanks for your response. I dont have that folder, the installation is on the “c:\Program Files (x86)\Universal”. I also did a search on the entire disk and nothing.

@jchera You can view the file suggested by @BuggeX in the admin console by navigating to Settings \ Configurations and then clicking the Repository \ .universal \ endpoints.ps1 file.

Gotcha, here you go, thank you.

Not sure if you changed endpoints after you created this post, but as far as I can tell, there
is no endpoint configured for test, so ofc the server would return 404.

I also don’t see an endpoint that has get-process, so i believe you mistook Automation/Scripts with APIs/Endpoints?
