PBI API limit exceeded error when trying to copy Notebook on Fabric

Hi,   I have a workspace with F4 capacity, where I am running Notebooks and Pipelines. My account itself does not seem to have the same capacity as the one associated with the workspace (my account...

    Hi PyyneCST ,

    Thank you for the update.

    The HTTP 429 error indicates request throttling on the Fabric/Power BI service side. Even though the operation was simply duplicating a Notebook, this action can internally trigger multiple Power BI REST API calls (for example, retrieving metadata, copying artifacts, permissions, and workspace item registration). If several operations occur within a short time window, the service may temporarily enforce throttling.

    Currently, the exact request limits for many Fabric operations are not publicly documented, as they can vary depending on factors such as capacity load, concurrent requests, and backend service protection policies. This is why the documentation does not list a fixed limit.

    Since the issue resolved automatically, it confirms the throttling was temporary service-side protection rather than a configuration problem with your account or workspace capacity.

    If the issue starts occurring frequently, we recommend:

    Monitoring capacity metrics for spikes in activity
    Avoiding rapid repeated artifact operations (copy/create/update)

    Implementing retry logic with backoff when automating Fabric API operations

    Please let us know if the issue reoccurs or if additional details are needed.

    Best Regards,
    Chaithra E.

HI PyyneCST  I think tayloramy  summarizes perfectly "Capacities are attached to workspaces, not to accounts", for instance, in the image below is two examples, in red shows my license to be premium per user (formely power bi pro) and in gray Microsoft Fabric (Free) ... this has nothing to do with the capacity assigned to the workspace 

 

 

What you need to check is the capacity of the workspace, you can check this by click on the workspace settings > workspace type and check on the details sectinos as shown below. 

 

 

With regards to the error, I'm guessing the pipeline runs some task related to Power BI, most likely I would assume you are orchestrating the refresh of the semantic model? If so, this error is basically the capacity on the workspace you'ære using it's hitting its limit and throttling in response sending you the 429 error. 

 

There's no solution other than wait for the throttling  to subside and/or increse your workspace capacity. 

 

Hope this helps, if so, a thumbs up will be nice and mark this as a solution if appropiate. All the best.
