If i return source map from the RolldownMagicString["generateMap"];
Type check fails.
export default {
transform: {
order: "post",
handler(this, code, id) {
const ms = new RolldownMagicString(code);
// Do Something with the string
// Error Here
const result = { code: ms, map: ms.generateMap({ hires: true }) } satisfies TransformResult;
return result;
},
},
}What is expected?
tsc does not fail
What is actually happening?
This because BindingSourceMap has `get sourcesContent(): Array<string | undefined | null>;``
And ExistingRawSourceMap has sourcesContent?: (string | null)[];
i would like to avoid using strictNullChecks: false
