Hey @N8_Nguy_n_Ng_c_Phu,

Welcome to the community

Did you always have hte credential test or was it something you added after testing an earlier version? It could be that the change is not being picked up because n8n wasn’t restarted. Are you able to share a link to the actual code for your node so I can test it locally?
