hi, looking at the looking you sent, the console.log is not inside a useEffect, but rather inside the component, so it will run every time the component re-renders. Have you modified this since you wrote the issue?

@alexnm Hello, I am refering to the console.log in the Component.txs. The console.log(obj) is in useEffect, and I think it should only run once.
