Error detected while processing BufWritePre Autocommands for "*.go"

In process of migrating to native NeoVim LSP got the error:

Error detected while processing BufWritePre Autocommands for "*.go":
E5108: Error executing lua [string ":lua"]:1: attempt to call global 'goimports' (a nil value)

In general this autocmd BufWritePre *.go lua goimports(1000) setting cause that error.
Still not sure why is that.
