Dataflow Gen2 (CI/CD) Data Pipeline Activity Fails when Dynamic Parameters Passed from Data Pipeline

Hi Fellow Fabricators,

This one gave me a nasty headache, so I'm posting here to help others with the same issue.

Error code: 20302

Failure type: User configuration issue

Details

Dataflow refresh job failed with status: Failed. Failure reason: { requestId: [guid], errorCode: 105004, message: . Learn more at https://go.microsoft.com/fwlink/?linkid=2314100 }

Error Link: Troubleshoot connectors - Microsoft Fabric | Microsoft Learn

The error code Troubleshoot guide is generic and the failure reason message is missing.

High-level config details

DataflowGen2 (CI/CD):

public parameters mode enabled
runs successfully when (using "current value" in parameters)

executed manually (save, run & close)
refreshed (manually) from UI

run fails

when called from a dataflow activity in a data pipeline, and
pipeline passes 3 dynamic parameters into dataflow

MICROSOFT RESOURCES

Dataflow Gen2 CI/CD - in GA May 2025

Deployment Pipeline Parameters are supported

Data Pipelines: Dataflow Activity supports Dataflow Gen2 CI/CD

Passing parameters into a Dataflow Gen2 CI/CD from a Data Pipeline activity is supported: and referenced thus

"When selecting a Dataflow Gen2 with CI/CD that has the public parameters mode enabled, a Dataflow parameters section is displayed which lists all the available parameters, their types, and default values for the selected Dataflow."

SOLUTION

After a lot of config tweaking to identify the root cause, it was a simple data typing issue (of course!!).

Parameters in data pipeline items must be strongly typed - mine were of type [String]

The DFG2 parameters were of type Any - this is usually really forgiving.

By changing the data type of all parameters in DFG2 to [Text] the DPL activity ran perfectly.

NOTES:

The error could be much more meaningful - and indeed the documentation should be updated to make this data type match requirement clear.
Dataflows and Data Pipelines have different development stories:
1. Dataflows have evolved considerably since their origin in Excel Power Query (aka Data Explorer)
2. Fabric data pipelines began life in Azure Data Factory - with some Azure Synapse pipeline DNA.
It is clear that these Fabric items are still not fully consistent - not least because types String and Text are not interchangeable/identical at a technical level 😛
