Root Cause

Go syntax error. Common causes: missing comma in multi-line args, brace on wrong line.

generic

Workarounds

  1. 95% success In multi-line function calls/slices, add trailing comma on last element
    f(
      arg1,
      arg2,  // trailing comma required
    )

  2. 92% success Opening brace { must be on the same line as if/for/func in Go
    func main() {  // correct
    // func main()\n{  // WRONG

Dead Ends

Common approaches that don't work:

  1. Ignore and rely on gofmt 80% fail

    gofmt can't fix syntax errors — it requires valid Go code

  2. Rewrite in a different style 70% fail

    The issue is usually a specific missing token, not style
