account.fetch does not fetch an existing account.

[HareemSaad]

try {
      await program.methods
      .initializeVesting(
        seedString,
        totalAmount,
        startTime,
        endTime,
        cliffPeriod,
      )
      .accounts({
        payer: signer.publicKey,
        mint: mint,
        beneficiary: signer.publicKey,
      })
      .signers([signer])
      .rpc();
    } catch (error) {
      console.log(error)
    }

    await delay(1000);

    const x = await connection.getAccountInfo(vestingAccount);
    console.log(x);

    const account = await program.account.vestingAccount.fetch(vestingAccount, "finalized");

    assert.ok(account.amount.eq(totalAmount), "Amounts do not match");

The issue is simple. I call this initializeVesting method, It is successful, as indicated by logs. and if i use connection.getAccountInfo I get a fully created account

but when fetching accounts using program.account.vestingAccount.fetch it produces error
