after file widget, edit domain widget add and edit domain, this error not happened.
why?

[jolo-maker]

Inserting an Edit Domain widget does not help. Did you select one of the features for seasonal adjustment in the Seasonal Adjustment widget? Without a selection of a feature everything passes through unchanged, but we want to see the breaking down into trend, season and residual line plots right?

Edit Domain widget add, and change variable name . That variable type is time.
Then this error not happened on my case.
Why?

• Operating system: Microsoft Windows 11 Pro
• Orange version: 3.37
• Timeseries add-on version: 0.6.3
• wsl (debian)

Originally, I was reading in data without headers using the "File" widget and performing seasonal adjustment processing. The data consisted of two columns: one with the date and time recorded as features, and the other being the target data.
Since there were no headers, I changed the variable names using the "Edit Domain" widget partway through. At that time, I was able to perform seasonal adjustment without any issues.

However, when I tried to perform seasonal adjustment on data with column names added as headers, I encountered an error saying "variable ●● is not domain," and I was no longer able to perform the seasonal adjustment.

Yes! Changing the time variable name in the Edit Domain does the trick! Unclear to me is why this is the case but the most important thing is that it works now, see picture.
Thanks!
