@RajabNatshah
Did you found this on 5.1.0 or 5.1.1?

Thank you for following up

#3138991: Fix schema mapping for Bootstrap Barrio
https://www.drupal.org/project/bootstrap_barrio/issues/3138991#comment-1...

If you are using the mapping: in the .schema.yml file
as in the following example
https://git.drupalcode.org/project/mayo/-/blob/8.x-1.x/config/schema/may...
But you do have it as
https://git.drupalcode.org/project/bootstrap_barrio/-/blob/8.x-4.x/confi...

Is the mapping in the bootstrap_barrio.settings: needed or each config schema will be in file or a config value?

Properly use config schema for theme settings

Thank you Alberto for maintaining the Barrio base theme
And for all time you put into it.

#3170658: Upgrade [Bootstrap Barrio] base theme from ~4.0 to ~5.0

Not sure if you had a look at comment #10

Thank you Alberto
Happy for having
