Creating an Azure Logic App with Powershell not working

Question

Creating an Azure Logic App with Powershell not working

Debbie Edwards 526

Im using the documentation to create a logic app with powershell

New-AzLogicApp -ResourceGroupName "dev-uks-project-rg" -Name " dev-uks-
project-logic" -Location " UKSouth" -State "Enabled" -DefinitionFilePath ".\workflows\ 
projectDefinition.json" -ParameterFilePath ".\workflows\projectParameters.json"

But it errors

New-AzLogicApp : File '.\workflows\ Projectefinition.json' does not exist.

At line:1 char:1

+ New-AzLogicApp -ResourceGroupName "dev-uks-project-rg" -Name " dev- ...

But no where does it explain what you need to do to get this working. I know the JSON files aren't there but what do I do? Is this a manual process? any help would be great because the documentation just doesnt cover this

@Debbie Edwards Edwards Thank you for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

Could you please help us with the documentation link that you are referring to create a logic app using PowerShell ?

I have come across this documentation, where it is clearly mentioned that before you create\update the logic app using Azure PowerShell you need to create a workflow definition(JSON formatted file) for your logic app.

Then you need to pass the path of the workflow definition file to -DefinitionFilePath property for New-AzLogicApp cmdlet.

Feel free to reach back to me if you have any further questions on this.

Workflow definition

Before you create a new logic app or update an existing logic app by using Azure PowerShell, you need a workflow definition for your logic app. In the Azure portal, you can view your logic app's underlying workflow definition in JSON format by switching from Designer view to Code view.

When you run the commands to create or update your logic app, your workflow definition is uploaded as a required parameter (Definition) or (DefinitionFilePath) depending on the parameter set. You must create your workflow definition as a JSON file that follows the Workflow Definition Language schema.

I'm afraid I dont understand this section that you are referring to.How can I view a logic apps underlying workflow definition when it doesnt exist yet?

@Debbie Edwards Thanks for your follow-up question on this.

The documentation which I have shared in earlier response is to create logic app using PowerShell module.

Yes, If you are trying to create new logic app from scratch then you need to create the workflow definition file and if you are trying to update the existing workflow then you can get the workflow definition file from the portal using Designer code view and you can pass that definition file to appropriate PowerShell cmdlet.

The workflow definition section talks about both create or updating the existing logic app in first line and later on how to get the workflow definition from the portal using designer code view.

I am checking with documentation author team internally to check if this documentation need to be updated.

Ahhhh. SO looking at the doc about the structure.... There is still nothing to say how you create it and where you save it to in Azure. And judging by the document https://learn.microsoft.com/en-us/azure/logic-apps/logic-apps-workflow-definition-language

I wouldn't have a clue where to start with that before I create a Logic App. How would you know how to set this all up without starting on your logic app? Or do you just add a blank template? from the documentation provided, it Looks like this is completely beyond my capabilities and I will have to always create manually.

Unless there is other documentation explaining how to do the bits it doesn't mention?

@Debbie Edwards Thanks for your response. You need to create those workflowdefiniton.json in your local machine(if you are deploying from localmachine) using any other editors like notepad or visualstudio code and pass the path of those files to the -Definition property as shown in this example here

This documentation Workflow Definition language schema talks about what should be added in the workflow definition.json file (like triggers,parameters,actions etc.,)

For reference you go through the sample quickstart arm template to create the consumption based logic app.

If you still feel documentation enhancement is required then I would suggest you to raise a documentation feedback as shown below

New-AzLogicApp -ResourceGroupName "dev-uks-project-rg" -Name " dev-uks- project-logic" -Location " UKSouth" -State "Enabled" -DefinitionFilePath ".\workflows\ projectDefinition.json" -ParameterFilePath ".\workflows\projectParameters.json"

So looking at the original code I set up. can I just create template files with no updated information in them (As is from the link you sent)? Or do I have to know everything from the beginning and set up?

'You need to create those workflowdefiniton.json in your local machine(if you are deploying from localmachine)'

I am using visual Studio powershell and connecting to Azure, am I deploying from local? I dont know the answer to this. I thought I was deploying straight to Azure?

And where would I create these two files on my local machine? I still don't have the answer to that either? Apologies, I have only just startied using Powershell to do this and it feels like there is a lot of assumed knowledge here?

@Debbie Edwards

The sample QuickStart logic app template (github) that is shared in my earlier response is to create consumption-based logic app with recurrence as trigger. Based on your requirement you need to create a workflow definition file from the beginning with the suitable triggers and actions that are needed.

I am using visual Studio PowerShell and connecting to Azure, am I deploying from local? I dont know the answer to this. I thought I was deploying straight to Azure?

Yes, you are deploying/creating the logic app from your PC/local/remote machine.

And where would I create these two files on my local machine? I still don't have the answer to that either? Apologies, I have only just started using PowerShell to do this and it feels like there is a lot of assumed knowledge here?

You can create those two file in any of the drive that are available on your pc/local machine and pass that respective path to -definitionfilepath property in New-AzLogicApp cmdlet.
