Not able to create Azure Logic App workflow using Visual Studio Code

Trying to follow this tutorial.

When I right click the workflow.json and select Open in Designer, I finally get the following message.

[2021-11-11T16:25:32.880Z] A host error has occurred during startup operation 'ae98f37d-d7d4-4131-920d-a725de7dc6cb'.

I even updated the csproj file with the command

dotnet add package Microsoft.Azure.WebJobs.Extensions.EventHubs --version 4.3.0

But the problem persisted.

Also as you can see, the designer tries to fetch something, and it says it Failed to fetch

And finally as you can see in the bottom right of the image, I get this message

Workflow validation failed: request to http://localhost:8000/runtime/webhooks/workflow/api/management/workflows/Stateful1/validate?api-version=2019-10-01-edge-preview failed, reason: connect ECONNREFUSED 127.0.0.1:8000. The source indicated is Azure Logic Apps (Standard) (Extension)

Any ideas?

I found one more YouTube tutorial but I am not able to get that working on my machine.

Raised issue here as well on github.

Solution

i had the same issue. In my case the solution was to go under Control Panel and uninstall Azure Function Core Tool (4.x) (if available). Afterwards open your Powershell and run following command:

npm install -g azure-functions-core-tools@3 --unsafe-perm false
