Virtual Agent action but no Flows to select

Posted on by Community Power Pla... Microsoft Employee

Hi all,

First time posting here. Recently started working with the Virtual Agent and I'm trying to add an action (Flow) that I have in Power Automate. I believe I have done everything correctly - but clearly I'm missing something as the Flow is no provided for selection.

I created a Flow in My Flows, I subsequently created a new Solution (within the same Environment as the Bot) and added the existing Flow from My Flows. Following these guidelines as suggested: https://docs.microsoft.com/en-us/power-virtual-agents/advanced-flow#move-a-flow-to-the-solutions-tab-on-the-microsoft-automate-portal

However, I still cannot see the Flow when trying to add an action within the authoring canvas. I then found another article suggesting that the Flow should be in the CDS Solution but that doesn't work either. Does anyone have any suggestions to help resolve?

Thanks,

Josh

Hi Josh,

There are several common reasons why you would not see a flow in Action picker in Power VA.

Bots can only invoke flows that have HTTP Request interfaces, so you need to select the right trigger for your flow. Make sure to use When Http Request is received trigger, as t is shown in the template.
Make sure you are using the POST method under advanced options in the HTTP Request trigger (or leave the method field empty, which is how it is by default).

You need to use variable types supported by Power Virtual Agents in your flow. The supported variable types in Virtual Agents that can be used with flows are:
String
Number
Boolean
Note that Arrays (Lists) are currently not supported in Power Virtual Agents. If unsupported variables types like Arrays (Lists) are used in a flow,it will not show up in Action picker.

If a flow has a malformed Request or Response JSON Shema or Body, Power Virtual Agents will not be able to recognize as valid and this flow will not show up in the flow picker in Action node.

I wrote an article on how to do this: https://d365goddess.com/power-virtual-agent-power-automate/

There is a new feature inside call an action to Create a Flow which will spin up a template with a sample input and output string. From there you should be able to easily modify it and insert your custom flow steps in the space just after the initialize variables steps provided.

@D365Goddess- Nice article! Keep em coming!

Hi @MarKol ,
I was wondering If I use an array list within a flow, but the trigger and outputs of the flow are all strings, should that work?

I've created a flow that appends all entities of the array to a string before outputting, but it isn't listed in 'call an action'. I'm trying to rule out if it's my error or not.

Thanks
Nicky

Nevermind, it was a malformed JSON schema on the end node. Might be worth to noting you can append items from an array to string to output though

Hi MarKol,

I'm receiving the same issue as JoshT14. The solution you provided did not resolve this issue. I have a pretty simple flow that takes in two string types to query a sql table.

Do you have any other ideas on what may be causing this issue?

Thank you,

Kian

So far, every time I have seen this it has been due to the JSON being incorrect or the flow not being in the 'solutions' areas. I'd say dig up the articles on those two things and I bet you will find they show up.
