Couldn't create a report

Hello everyone

I’ve read the documentation of the reporter app
but I couldn’t create any report

I know it’s a simple thing but I keep getting this error message
“Failed to run report: failed to validate the model. no model steps defined”

any idea what I’m doing wrong ?

What does the report look like? Did you define any sources and display elements?
Based on the report you are trying to run an empty report.
