Issue with Netlify deploy

I’m using the Hyde theme. I added it as a submodule, but Netlify is failing to deploy the website in the Initializing stage:

I set the Hugo version to 0.115.2.

How did you do this?

i would add https://sweet-froyo-741890.netlify.app/ to your config.toml instead of https://sweet-froyo-741890.netlify.app

in terminal, git submodule add {theme on github} {themes directory on local harddrive}

that worked! thank you so much.
