Troubleshoot Activator errors

  • Article

If a problem occurs with any of your Fabric Activator events, objects, or rules after you create them, then Fabric Activator sends you an email containing an error code. This article explains the meaning of the error codes that you can receive and describes the steps to take to fix the associated problems.

Data ingestion error codes

The following error codes represent problems that can occur when Activator ingests data from Power BI semantic models and eventstream items.

PowerBiSourceNotFoundOrInsufficientPermission

Activator can't access the Power BI semantic model for your object. This error occurs if the dataset is deleted or if permissions on the dataset change since you created the alert. To resolve the problem, check if the dataset still exists, and:

  • If the dataset exists, ensure that you have permission to access it.

  • If the dataset is deleted, then your objects and rules don't function. Delete then recreate them as needed on another semantic model.

QueryEvaluationError

Activator can't query the Power BI semantic model for your object. This error occurs if the structure of the dataset changes after you create the alert. To resolve the problem, either:

  • Restore the original structure of your semantic model, or
  • Delete your Activator object and recreate your rule against the semantic model.

EventHubNotFound

Activator can't find the Fabric eventstream for your object. This error occurs if the eventstream for your object is deleted, or if the connection from your eventstream to your Activator item is removed. To resolve the problem, reconnect a Fabric eventstream to your Activator object.

EventHubException

Activator receives an exception from eventstreams when importing your data from your eventstream item. To resolve the problem, open your eventstream item and examine the connection to your Activator object and check for errors in the connection or the eventstream.

UnauthorizedAccess

Activator isn't authorized to access the eventstream item for your Activator object. This occurs when permissions on the eventstream item change since you connected your Eventstream item to Activator. To resolve the problem, make sure that you have permission to access the eventstream item.

IncorrectDataFormat

The eventstream item connected to your Activator object contains data in a format that isn't recognized by Activator. To resolve the problem, review the data in your eventstream item to ensure that it's in JSON dictionary format, as described in Get data for Fabric Activator from eventstreams.

Rule evaluation error codes

The following error codes represent problems that can occur when Activator evaluates your rule condition to see if the condition is met.

ProcessingLimitsReached

Your rule exceeds data processing limits for one of two reasons:

  • You're sending too many events per second to your Activator object, or
  • Your rule is activating too frequently.

There are two ways to resolve this problem. Try reducing the number of events per second that you're sending to your object. Or, update your rule to activate less frequently.

WorkspaceCapacityDeallocated

The Fabric capacity for your rule's workspace is deallocated, so you no longer have Fabric capacity available to process your rule. To resolve this problem, contact your Fabric capacity administrator to ensure that you have a Fabric capacity assigned to your rule's workspace.

DefinitionFailedValidation

This error code means that your rule definition is invalid. It indicates an internal problem with Activator. If you receive this error code, ask for assistance on the Activator community site.

MaxDelayReached

The error code means that Activator is unable to receive incoming data for your rule for the past seven days, and is not evaluating your rule. It indicates an internal problem with Activator. If you receive this error code, ask for assistance on the Activator community site.

Exceeded capacity error codes

The following error codes represent Activator problems that can occur when your account runs out of Fabric capacity.

CapacityLimitExceeded

Your account exceeded the limit of your Fabric capacity for more than 24 hours. When you exceed your capacity, throttling policies are applied and Activator pauses rules evaluation, background operations, and activations. To resolve this problem, contact your capacity administrator and ask them to review capacity usage and upgrade as needed. Once your capacity issue is resolved, make sure to reactivate your rules.

Alert and Action Error codes

The following error codes represent problems that can occur when Activator attempts to send an alert, or to start a Power Automate flow, after a rule condition is met.

UserNotFound

This error code means that Activator couldn't locate the recipient of your rule's email or Teams alert. To resolve this problem, review the recipient field on your rule's action card and make sure that it's set to a valid member of your organization.

RecipientThrottled

This error code means that Activator couldn't alert the recipient of your rule because the recipient receives too many messages from Activator. The article Activator limitations lists the maximum number of messages that you can send from a rule. To resolve this problem, change the definition of your rule so that it activates less often.

BotBlockedByUser

This error code means that you have a rule that sends a Teams alert, and the recipient of the alert blocks the Activator bot from sending them messages. To resolve this problem, ask the recipient to unblock the bot.

TeamsAppBlockedInTenant

This error code means that you have a rule that sends a Teams alert, and your Teams administrator blocks the Activator app. To resolve this problem, ask your Teams administrator to unblock the Activator Teams app.

OfficeSubscriptionMissing

This error code means that Activator couldn't send the alert on your rule because you don't have a Microsoft Office subscription. To resolve the problem, get a Microsoft Office subscription.

TeamsDisabled

This error code means that you have a rule that sends a Teams alert, and that the administrator of your Microsoft Entra tenant blocks the Microsoft Teams service principal (SP). To resolve the problem, contact your Microsoft Entra administrator and request that they unblock the Teams SP.
