ast parse ExportNamedDeclaration type, source filed maybe null

[cizkey]

in my project , i encounter an error "[vite] Internal server error: Cannot read property 'value' of null"

it seems getAvailableExportsFromAst in ast.ts has bug.

 const addExport = (node: ExportNamedDeclaration) => {
    for (const specifier of node.specifiers) {
      if (specifier.type === 'ExportSpecifier' && specifier.exported.type === 'Identifier') {
        console.log('----max---', node) // console logs
        exports.push({
          start: specifier.exported.start!,
          end: specifier.local.end!,
          imported: specifier.exported.name,
          local: specifier.local.name,
          path: node.source.value // notice this line
        })
      }
    }
  }

i console the node, got some logs:

the node.source maybe null value , is it should use node.source?.value to fixed it ?

I think this is the second time this has been reported. Can you provide a reproduction for this, I'm not quite sure what is causing it yet

I was the one who reported last time.

i think it caused by some ts file have not export default statements.

i made a reproduce demo:
