Cannot install plugins

I have this error when I try to install a plugin:

bin/opensearch-dashboards-plugin install queryWorkbenchDashboards --allow-root
Found previous install attempt. Deleting...
Attempting to transfer from queryWorkbenchDashboards

Plugin installation was unsuccessful due to error "No valid url specified."

I have opensearch dashboards 1.2.0 installed

No one was able to review my question?, I still can’t install the plugins
