Cant re-add a flow to PVA after I have updated it

Posted on by niknaks456

Hello all, not sure if this is a bug or 'm just doing silly.

I had a PVA working fine and then I added something more to a flow. The PVA told me I needed to remove and read the flow to get the changes. I removed and went to add the flow from the 'call an action option' option. From here I can see my flow fine but when I click to add it back into my PVA it simply wont. I can add other new flows just fine but not the one I updated.

I have tried different browsers, logging in and out. If I recreate the same flow with a new name I can add the flow to my PVA but that's a real pain for ongoing development every time I need to change a flow.

Any clues on how to fix this. Also is there a way to just update the flow in the PVA with an update button?

Hi @MarKol ,
Thanks for the answer. I removed all spaces and special characters and finally I could use my Flow.
Regards,

Chrome and Edge both show the same stack trace when you try to select one of these unselectable actions:

turns out that the issue I experienced with variable names of length>10 only causes upset in one bot, and not another.
so, there's something else going on

Through a process of trial and error I think I found an underlying problem.

Any variable name returned by the "Return value(s) to Power Virtual Agents" must be no more than 10 characters long. I think removing whitespace just shortened the names below 10 chars.
Anything 11 or more means that when you attempt to add the action to a PVA topic, it will just ignore the attempt to add.

This one works:
While this won't:

Re: Cant re-add a flow to PVA after I have updated it

I ran into this today--I have several virtual agent topics that call actions that return text strings. Today I created a new flow, but couldn't add it to a topic; I'd select Call action, then select the flow name, and nothing would happen. I took the numbers out of the title of the flow output, and then I could select the flow name and the flow would be added to the topic.

So "alphanumeric characters" doesn't quite fit. Letters work, underscores work. Numbers don't work.

hmm, i think i have it sorted now via your help.

I removed numbers from the return values, so I had '365prinname' as the name of the return value and removed '365' which seems to have fixed it. I also took out number in the name of the flow as well just in case.

Hi,

can you please try remove any spaces or other non-alphanumeric characters (underscores are OK) from the flow's inputs/outputs and try adding this flow again?

There is a bug currently being fixed that makes PVA reject the flows with non-alphanumeric characters as valid. This workaround should make PVA accept this flow.

PS: the "Refresh" button for flows is on the roadmap and should be coming soon.

Hi @niknaks456 ,

It's not normal this issue.
Can you take some pictures inside your Power Automate workflow?
Just to understand better your scenario, but depending on your situation, you can open a ticket to Microsoft.
