Lesson 5: const updatedNumber = await contract.retrieve(); Not working!!

[AGMASO]

Hello dear Colleagues,

I'm having a curious error when following the Lesson and deploying the Smart Contract to the Alchemy Testnet Blockchain.

Issue:

const currentFavoriteNumber = await contract.retrieve(); 

  console.log(
    `Default Favorite Number: ${currentFavoriteNumber.toString()}`
  );

  await contract.store("10");

  const updatedNumber = await contract.retrieve();
  console.log(`New Favorite Number: ${updatedNumber.toString()}`);

This code is working perfectly on Ganache Local TestNet. When I change the setup to be connected to Alchemy Testnet, the same code do not work.

After this piece of code const updatedNumber = await contract.retrieve();
The console should show the number 10, but it shows number 0. I repeat only when I'm connected to Alchemy. I have checked that the asynchronous function : await contract.store("10"); is working, but somehow the console.log do not show the right number.

Some Ideas or solution?

Thank you in advance!

@AGMASO Hey! Add a waiting condition after storing a number, because testnets takes time to update that.

await contract.store("10");
await contract.deployTransaction.wait(1);

Hello! @alymurtazamemon

Thank you for the solution. Somehow It also didn't work waiting just 1 block. I had to code :

await contract.deployTransaction.wait(3);

Thank you again for your help
