Pass filename dynamically in dataflow synapse pipeline - source as excel

I am trying to pass filename as parameter to dataflow in synapse pipeline but facing issues.

I am setting a variable and passing that to dataflow as below.

Also created a parameter inside the dataflow

Also inside source

Inside connection given filepath as

Wildcard path under source as

When I try to import projection getting error. No idea about this, appreciate your help in resolving this. I suspect may be I am doing something wrong in passing parameters?

This is the file which I am trying to access in source

If you want to pass filename as parameter to dataflow follow below procedure:

Create dataset string parameter fileName for dataset as shown below:

Create pipeline string parameter fileName with value as shown below:

Provide above parameter as set variable value @pipeline().parameters.fileName as shown below:

In data flow provide the variable fileName which is created in set variable activity to the data flow @variables('fileName') as shown below:

Then you will be able to pass file name successfully without any error.

Note: No need to create parameters in data flow to pass file name while parameter created in dataset.
