Unable to run ic-nns-init: Internal Server Error

I was trying to deploy and run NNS locally, so I followed the following steps:

git clone --branch rc--2021-11-29_18-31 --depth 1 https://github.com/dfinity/ic.git
cd ic/gitlab-ci/tools
cd ../../rs
cp ../artifacts/canisters/* target/wasm32-unknown-unknown/release/
find *.gz | xargs -I {} gzip -df {}
cd ../../../nns
dfx start --host # Blocks, open a new terminal
cd ..
cargo run --bin ic-nns-init -- --url http://localhost:8080/ --wasm-dir=./target/wasm32-unknown-unknown/release

It was built successfully, but I get the following error, repeatedly:

Retrying due to: HTTP Client: Request to http://localhost:8080/api/v2/canister/aaaaa-aa/call failed with "Internal Server Error", Ok("Internal Server Error")

Inside dfx terminal I got the following error:
