key file {} permission is not 600

Error message

key file {} permission is not 600

What it means

The second assertion in MergeNativeReport (src/pkg/scan/report/report.go): after r1 has already passed the *vuln.Report check, the SECOND operand r2 fails the same type assertion. The merge is between two untyped values routed through SupportedMergers, so any operand that is not exactly a *vuln.Report pointer (nil included) aborts the merge.

Solutions

  1. Filter or fail on any element of the report list that does not decode to *vuln.Report before merging
  2. Confirm both reports were resolved under the same mime type and the same SupportedMimes entry
  3. Log %T of both operands at the call site to identify the odd one out

Example fix

// before
merged, err := report.MergeNativeReport(nr1, r2) // r2 is `any`

// after
nr2, ok := r2.(*vuln.Report)
if !ok {
    return nil, fmt.Errorf("second operand is %T, want *vuln.Report", r2)
}
merged, err := report.MergeNativeReport(nr1, nr2)
Defensive patterns

Strategy: type-guard

Validate before calling

if !isNativeReport(r2) {
    return fmt.Errorf("second merge operand is %T, want *vuln.Report", r2)
}

Type guard

func isNativeReport(v any) bool {
    _, ok := v.(*vuln.Report)
    return ok
}

Try / catch

merged, err := report.MergeNativeReport(nr1, r2)
if err != nil && strings.Contains(err.Error(), "native report required") {
    return fmt.Errorf("r2 not a native report (%T); re-resolve it under the same mime type", r2)
}

Prevention

When it happens

Trigger: Merging reports collected from heterogeneous sources — e.g. r1 decoded via ResolveData into *vuln.Report but r2 loaded from a store, a different mime type, or a nil interface.

Common situations: Merging a freshly scanned report with a legacy or raw one; mixed mime types funnelled into one merge call; a report slice where one element failed to parse and was left nil.
