Describe the Bug with repro steps

Suddenly, I've started encountering an issue. Whenever I attempt to create or open a new map, I receive an error stating 'can't start the background design-time process'!

What version of the VSCode extension are you running?

Could you please check or try adding these values to the local.settings.json inside the workflow-designtime folder in your project? These properties should be inside the "Values" property "AzureWebJobsSecretStorageType": "Files", "APP_KIND": "workflowapp",

wiktorklusek commented 1 month ago

Hi Danielle,

Let me try that approach now

wiktorklusek commented 1 month ago

Here are the content of my file:

{ "IsEncrypted": false, "Values": { "FUNCTIONS_WORKER_RUNTIME": "node", "AzureWebJobsStorage": "UseDevelopmentStorage=true", "ProjectDirectoryPath": "c:\Users\admin\Samples\LogicAppMapperPOC", "AzureWebJobsSecretStorageType": "Files", "APP_KIND": "workflowapp", "Host": { "LocalHttpPort": 8080 } } }

Whenever I try to Select schema I get this error Failed to Fetch

DanielleCogs commented 1 month ago

@wiktorklusek I was able to reproduce the issue when I added the following to my local.settings.json. Are you able to remove this setting for now as a temporary workaround?

"Host": {
"LocalHttpPort": 8080
}

I do not think this is an issue specific to Data Mapper, as the same error happens when opening Designer.

DanielleCogs commented 1 month ago

Seems that we do not yet support being able to specify the port in this way. Is this a blocking scenario for you?

wiktorklusek commented 1 month ago

Once the "Host" was removed, I received the same issue. The two Azure Core Tool functions that typically load right at the start are not found by my setup.

wiktorklusek commented 1 month ago

I suspect I would need to reinstall the functions core tools, do you have any documentation for that? My extension is unable to locate functions required to run the data mapper.
