Troubleshooting Power Automate Triggers in Dataverse

There are scenarios in Power Automate where a flow is correctly configured, turned on, and yet does not get triggered at all, with no errors or run history available. One such lesser-known but critical cause is an issue with the CallbackRegistration record in Dataverse.

Each Dataverse trigger in Power Automate relies on an underlying CallbackRegistration record to listen for data changes. If this record becomes corrupted, stale, or improperly registered, the trigger silently stops working—even though the flow appears healthy in the Power Automate UI.

In this blog, I will highlight how a faulty CallbackRegistration record can prevent a flow from triggering and how deleting the specific record forces Dataverse to recreate it, thereby restoring normal trigger behavior without rebuilding the flow.


Step 1: Get the Workflow ID

Before identifying or deleting the problematic CallbackRegistration record, we need to determine the Workflow ID of the affected Power Automate flow. This ID uniquely identifies the flow within Dataverse and is required to locate the corresponding callback registration entry.

Every Power Automate flow created using a Dataverse trigger is stored internally as a Workflow record. The CallbackRegistration entity maintains a reference to this Workflow record to listen for create, update, or delete events on the target table.


Step 2: Retrieve the CallbackRegistration Record for the Flow

Once the Workflow ID is identified, the next step is to locate the corresponding CallbackRegistration record in Dataverse. This record links the Power Automate flow to the Dataverse event listener. If this record is corrupted or stale, the flow will not trigger.

You can retrieve the CallbackRegistration record using the Dataverse Web API, filtering by the Workflow ID.

https://<your-org>.crm.dynamics.com/api/data/v9.2/callbackregistrations?$filter=name eq '<WorkflowId>'

Step 3: Turn Off the Flow

Before making any changes to the CallbackRegistration record, it is important to turn off the Power Automate flow. This ensures that Dataverse releases the existing callback listener and prevents the flow from attempting to trigger while the registration record is being modified.


Step 4: Delete the CallbackRegistration Record Using Browser Console

After turning off the flow, the next step is to delete the identified CallbackRegistration record. This can be done directly using the Dataverse Web API from the browser console.

Steps:

  1. Open your Dynamics 365 / Dataverse environment in the browser.

  2. Open Developer Tools (F12 or right-click → Inspect).

  3. Navigate to the Console tab.

  4. Run the following generic command:

fetch(
  "https://<your-org>.crm.dynamics.com/api/data/v9.2/callbackregistrations(<CallbackRegistrationId>)",
  { method: "DELETE" }
);

Once deleted, Dataverse will automatically recreate a fresh CallbackRegistration record when the flow is turned back on.

Conclusion

After deleting the CallbackRegistration record, wait for a few minutes to allow Dataverse to fully clean up the existing trigger references. Once the wait period is complete, turn the Power Automate flow back on.

When the flow is enabled, Dataverse automatically creates a new callback registration record for the flow. At this point, try triggering the flow again by creating or updating a record based on the configured trigger.

In most cases, the flow should now trigger as expected, confirming that the issue was caused by a corrupted or stale CallbackRegistration record.

Create and Send Emails with Attachments in D365/Dataverse with Power Automate

Image
  With Power Automate, you can connect to over 300 connectors, including the Outlook connector that can send emails, which is great. However, if you are used to working with Dynamics 365 or Dataverse, one of the key advantages is tracking emails, and if you use the Outlook connector, you cannot do this. This post will show how to create an email, how to add an attachment and how to send an email, so that it’s tracked inside of D365/Dataverse. Create a file or attachment that you want to add onto an email, in my example, I'm going to carry on from my previous post about Word Templates. Then we will "Add a new row" using the Dataverse Connector and the Table name will be Email Message. This will create an email record/row in D365 which requires certain parameters. Firstly, the way email fields to, cc, bcc and from work in D365/Dataverse is via what is called an activity party list. This is a list of rows/GUIDs of rows inside of D365/Dataverse that the email message is conn...

Dynamics 365 CRM Form Switching: A Deep Dive into formSelector and navigate()

Image
In the dynamic landscape of Dynamics 365 Customer Relationship Management (CRM), the ability to present different forms to various user groups based on specific conditions is a common and powerful customization requirement. Fortunately, the formSelector object, coupled with the navigate() function, provides an elegant solution to this challenge, allowing for seamless form switching based on user roles and other criteria. FormSelector Object At the heart of this functionality lies the formSelector object, a JavaScript object that acts as a gateway to managing forms within Dynamics 365 CRM. The formSelector object grants access to a collection of items, representing all the forms accessible to the current user. It's important to note that these forms are filtered based on the user's security roles, ensuring a secure and controlled form-switching experience. Exploring the items Collection Within the formSelector object, the items collection stands out as a crucial repository...
