"Command not found: complete" message appears every time I open the terminal

I was setting up my development environment on Ubuntu 20.04 following a video on Youtube and after running the command

$ echo -e '\n. $HOME/.asdf/completions/asdf.bash'>> ~/.zshrc

Every time I open the terminal the message appears:

/home/gustavo/.asdf/completions/asdf.bash:80: command not found: complete

Does anyone know what I could have done wrong and how can I fix it?
