What's the issue:

The getting started docs on the semantic release webpage suggest the following example for commit exclusion.

To set commit exclusion patterns for a conventional commits parsers, add the following to your
pyproject.toml file:

.. code-block:: toml

[tool.semantic_release.changelog.exclude_commit_patterns]
# Recommended patterns for conventional commits parser that is scope aware
exclude_commit_patterns = [
    '''chore(?:\([^)]*?\))?: .+''',
    '''ci(?:\([^)]*?\))?: .+''',
    '''refactor(?:\([^)]*?\))?: .+''',
    '''style(?:\([^)]*?\))?: .+''',
    '''test(?:\([^)]*?\))?: .+''',
    '''build\((?!deps\): .+)''',
    '''Initial [Cc]ommit.*''',
]

Notably, there is a reference to the exclude_commit_patterns object itself.
Running this configuration in my pyproject.toml and using the demo:

> semantic-release -v --noop version

🛡 You are running in no-operation mode, because the '--noop' flag was supplied

Solution

Remove .exclude_commit_patterns substring from the toml identifier.
