I am creating a new build for my conda-forge package to reflect the change in se…tup files: from setup.py + requirements.txt to single pyproject.toml file.
I successfully used grayskull to produce the meta.yml on the 1st build (with the contents of requirements.txt being just conda), but now, the assertion made on line 165 of format_dependencies fails and I do not understand why.
** Envir **
miniconda on Windows 10
python 3.10
grayskull version: 2.2.2
** Steps**
I used this command to generate a meta.yml file for my repo:
`grayskull pypi https://github.com/CatChenal/new_conda_env`
This is my pyproject.toml file:
```
[build-system]
requires = ["setuptools", "setuptools-scm"]
build-backend = "setuptools.build_meta"
[project]
name = "new_conda_env"
description = "A Python package for generating a 'lean' environment yaml file (see README)."
version = "0.1.0"
license = "MIT license"
requires-python = ">=3.6"
keywords = ["conda", "env", "tool"]
dependencies = ["conda"] # fails
authors = [{name = "Cat Chenal"}]
[project.scripts]
new-conda-env = "new_conda_env.cli:main"
classifiers = [
"Development Status :: 2 - Pre-Alpha",
"Intended Audience :: Developers",
"License :: OSI Approved :: MIT License",
"Natural Language :: English",
"Programming Language :: Python :: 3.6",
"Programming Language :: Python :: 3.7",
"Programming Language :: Python :: 3.8",
"Programming Language :: Python :: 3.9",
"Programming Language :: Python :: 3.10",
]
[tool.setuptools.dynamic]
readme = {file = ["README.md"], content-type = "text/plain"}
```
Grayskull returns an error from `format_dependencies` with this Traceback:
```

File "C:\Users\me\miniconda3\envs\for_pkg\lib\site-packages\grayskull\utils.py", line 165, in format_dependencies
if deps_name.replace("-", "_") == name.replace("-", "_"):
AttributeError: 'NoneType' object has no attribute 'replace'
```
**Expected behavior**
No error?
What is the comparison on line 165 doing: ` deps_name.replace("-", "_") == name.replace("-", "_")`?
Why is it failing with my pyproject.toml, i.e. what is wrong with `dependencies = ["conda"]`?
Thanks for your help!
