Error on trigger of the Flow which reads as “The power flow’s logic app flow template was invalid”

This could be because the schema of the Flow is not longer valid and needs to be refreshed. Here’s a simple way on how you can do this.

Scenario

Let’s consider this Scenario where you have an On-Demand Flow in Dynamics 365 CRM which is using a Dataverse (Legacy) trigger –

1. You see the Flow as below in Dynamics 365 CRM on the record which you can call (Replacement of your classic On-Demand Workflows in CRM 😊)
   Flow didn’t run as expected and hence, the next step was to investigate.
   
   
2. So, to further investigate, you open the Flow and find this error notification already in the Edit mode itself.
   
   The complete error message reads as –
   “The power flow’s logic app flow template was invalid. The ‘type’ property of template trigger ‘manual’ at line ‘1’ and column ‘11024’ has the value ‘Manual’ which is deprecated in schema version ‘2016-04-01-preview’ and onwards.“
   
   
3. This means the Schema has been deprecated and you’ll need to refresh the same.
   

Fix

Here’s how you can quickly fix this –

1. Remove the trigger
   
   
   
2. And then re-add the same trigger. In this case, Dataverse (Legacy)
   
   
   
3. Note that the references will be removed since you removed this step/trigger.
   
   
   Now, for this particular Flow Trigger, I further faced issues while receiving the Body correctly. And got something like this –
   
   I’ll further investigate this and update this post
   
   Now, save the Flow and re-attempt Running it.
   Note: Since the schema has been updated, you’ll need to investigate the check the rest of the Flow for any changes you might need to make.
   
4. For Logic Apps, Microsoft Docs has provided this directive – https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-schema-2016-04-01#upgrade-your-schema?WT.mc_id=DX-MVP-5003911
