New “Invoke Pipeline (Fabric)” activity not executing, while Legacy version works

aayushiharalal — Thu, 19 Mar 2026 07:22:58 GMT

Hi all,

I’m running into an issue with the new Invoke Pipeline (Fabric) activity.

Context

I have an orchestration pipeline that calls another pipeline (fm_job_control).
The Legacy Invoke Pipeline activity works perfectly.
When I switch to the new Fabric Invoke Pipeline activity, it does not execute as expected.

Configuration Details

Type: Fabric
Connection: FabricDataPipelines (status: Online, verified in Connection Management)
Workspace: FM-Dev-Gold
Pipeline: fm_job_control
Parameter passed:
- MainPipeLineName = "<pipeline name>"
Wait on completion: Enabled

Observed Behavior

Legacy activity executes successfully with the same pipeline and parameters.
New Fabric activity:
- Does not trigger the downstream pipeline (or fails silently / does not behave as expected).
- No obvious connection issues (connection is online and refresh works).
- Configuration appears identical from a logical standpoint.

What I’ve Checked

Connection is valid and online.
Workspace and pipeline selection are correct.
Parameters match what works in the legacy version.
No obvious permission issues on workspace or pipeline.

Questions

Are there known limitations or behavioral differences between Legacy Invoke Pipeline and the new Fabric version?
Does the new activity require different parameter typing or schema definition?
Are there additional permission or identity requirements specific to Fabric pipelines?
Is there any known issue where the activity appears configured correctly but does not trigger execution?

Hi @aayushiharalal,

I have the new invoke activity in place and its working fine but without parameter.

May I ask you to share the error message of the invoke acitivity which fails?

Beside that, what I came across and might cause issues and what you can check:

- if you have PIM in place and the connection authentication is configured with a PIM identity it might fail depending on the pipeline schedule and PIM activation status

- the identity executing the pipeline has not sufficient rights for the pipeline connection

Hope this helps! Or we can dive deeper into the error message.

Best regards!

Hello @Mauro89 ,

I have created two pipelines in Microsoft Fabric:

A main pipeline, which invokes a child pipeline using the InvokeFabricPipeline operation

A child pipeline, which is a simple pipeline with no parameters or activities (for testing purposes)

However, when executing the main pipeline, I consistently receive the following error:

Error message
{"requestId":"3bd6a7a5-3fd3-420c-807a-f25ac091243e","errorCode":"ItemNotFound","message":"Could not found the requested item"}

}

Manage Connections

Clarifications:

Both pipelines are in the same workspace
I have Admin access to the workspace
The pipelineId and workspaceId were copied directly from the Fabric UI
The child pipeline is saved and visible
A valid connection is configured via Manage Connections (screenshot attached)

Request:

Could you please help clarify:

If there are any additional backend requirements (e.g., publishing state, hidden dependencies, or API limitations) for invoking a Fabric pipeline
Whether InvokeFabricPipeline has any known constraints related to workspace scoping or connection binding
If this error could indicate an issue with ID resolution on the service side, despite the item being present and accessible

Hi @aayushiharalal,

the invoke pipeline acitivty is basically very simple. There are not specific limitations like you mentioned.

What else you can try.

- Take you the legacy invoke (not sure if you call in both acitivities the same pipelines to invoke).

- OR create two complete new pipelines and invoke the one from the other just to check if there is any general issue in your environment

Best regards!

Hello @Mauro89 ,

I’ve already tried creating a completely new pipeline for testing (as shown in the screenshot in above reply), but the issue persists.

Both Invoke Pipeline activities are calling the same pipeline. I also created a new connection to rule out any connection-related issues, but that didn’t resolve the problem.

Because of this, I’m currently unable to work across workspaces.

At this point, I’m wondering:

Could this be related to tenant-level settings?
Are there any capacity limitations or configurations that might cause this behavior?

I’m running out of possible causes to investigate, so any guidance on what to check next would be really helpful.

Thank you.

Hi @aayushiharalal,

there is no tenant-level setting or capacity config which relates to the difference between the two activities.

Last thing what I can think of is that you check and compare both source codes of the pipelines. If there is nothing significant different, I recommend opening a support ticket at Microsoft.

Best regards!

Hello,
I wasn’t able to pinpoint the exact root cause, but moving to a Service Principal connection resolved the issue and the setup is now working as expected.

For anyone facing a similar problem, this approach might be worth trying.

Thanks to @Mauro89 for the support and time.

Hello @Mauro89,

In the legacy setup, invoking the pipeline did not require a connection, which is why it was working there. In the new setup, invoking the pipeline activity requires a connection, and this appears to have been the cause of the issue.

After switching to a Service Principal connection, the new pipeline activity is now working as expected.

Thank you for your time and support—it was very helpful.🙂

Hi @aayushiharalal

Thank you for sharing the update and resolution. Glad to hear that switching to a Service Principal connection resolved the issue.

If any of the responses helped, please consider acknowledging or marking it as the solution so it can help others facing a similar issue in the future.
