%s: upload video code=%d msg=%s

Error message

%s: upload video code=%d msg=%s

What it means

The Feishu file-upload API returned an HTTP 200 response but with a non-success business code (uploadResp.Success() false). The error surfaces the API code and msg so the developer can map it to Feishu's documented error-code table.

Solutions

  1. Read code=%d in the message and look it up in Feishu Open Platform error-code docs
  2. Ensure the app has the im:resource (or im:file) permission scope approved and published
  3. Verify the video format/extension is supported and within size limits
  4. Re-upload after fixing; the error is deterministic for bad requests
  5. Check that the tenant_access_token corresponds to the same app that owns the permissions

Example fix

// before: only err checked, non-success code not handled distinctly
if err != nil { return ... }
// after: also log code/msg upstream and alert on permission-class codes
if !uploadResp.Success() {
    slog.Error("feishu upload failed", "code", uploadResp.Code, "msg", uploadResp.Msg)
    return fmt.Errorf("%s: upload video code=%d msg=%s", p.tag(), uploadResp.Code, uploadResp.Msg)
}
Defensive patterns

Strategy: try-catch

Try / catch

if err := sendVideo(...); err != nil {
    if strings.Contains(err.Error(), "code=") {
        // parse code and consult Feishu error-code table
    }
}

Prevention

When it happens

Trigger: client.Im.File.Create returns a response whose Success() is false during video upload — e.g. invalid file format, file exceeds size limits, missing scopes (im:resource), or app permission problems.

Common situations: App missing im:resource scope; video format not in allowed list (mp4 etc.); file larger than Feishu's 30MB limit for message files; bot not in the target chat causing permission codes.
