Help for Aimeos

Hi,
I'm sorry for silly question maybe, but I installed aimeos shop extension in my Typo3 site to test its backend.
I go to Aimeos backend to Product
I enter data into Basic, Images, Text, Prices,Characteristics (entered in advance), Options (entered in advance) I select Category (entered in advance)
and I see an error in red
No item found for conditions: Array ( [attribute.code] => custom [attribute.domain] => product [attribute.type.code] => price [attribute.type.domain] => product )
I see that "products" below Options is empty and red line appears there.

I want to enter Article only.

Thank you in advance

You've deleted the custom price attribute from the attribute panel. Execute the update script in the Extension Manager to add it again.
