I have installed vanilla sitecore commerce version 9.3 on my local machine. I have created a new environment "CustomEnvironment" and created a new catalog "client_catalog" and created "client_pricebook".

Now i am trying to associate the pricebook to the catalog by by associating catalog in pricebook section. But i am getting an error "Catalog name already in use"

I have tried to clean environment,bootstrap environment and initialize environment as suggested in sitecore documentation but it is still showing the same error.

Any suggestions?
