) {}

Fixed code:

const someFn = (a, b) => {};

It looks like getSourceCode() used to rewrite the function body is now deprecated and instead context.sourceCode should be used. Here is some documentation on how eslint API handles comments: https://eslint.org/docs/latest/extend/custom-rules#accessing-the-source-text

In case you're interested, I ended up rolling my own solution which makes autofixes with more precision: https://github.com/privatenumber/lintroll/tree/develop/src/custom-rules/prefer-arrow-functions
