addr1=WYONSEI7LNHTX44M72JPTGUCNQMUQXP5KMXEIK7HFV6FWKHZ6DSCIDBMXM
addr2=IE7H6VK6MHXFQXZAMGFALZVIBJO5KL7EMXSM7G7L3VBN4U

I am sending 0.784485 ALGO at addr1 to addr2
I set the transaction fee to 0.001 ALGO, which is the minimum fee. But when posting the signed transaction, an error occurs in the screenshot.

The transaction object I signed

{

This error means that is if the transaction were to go through that either:
WYONSEI7LNHTX44M72JPTGUCNQMUQXP5KMXEIK7HFV6FWKHZ6DSCIDBMXM does not have enough funds to cover the transaction or that if it does it will drop below the minimum required balance. Use the dispencer and add more funds to the account.

What is dispencer ?
The sum of fee and amount I have defined is equal to the total of the balance at the address.Doesn’t the fee element in transaction object show the maximum amount of fee?

The dispenser is for testnet and betanet for testing an app. It is a token faucet: https://bank.testnet.algorand.network/

You can not leave the account at 0 unless you use the closeRemainderTo parameter of a transaction.
https://developer.algorand.org/docs/reference/transactions/#payment-transaction

you can use suggested fee for just put in a flat fee of 1000 microAlgos:

I fill the closeRemainderTo parameter to be the same as the to parameter. But the same error occurs again.

When I try to apply the example under the Using a Flat Fee header, I get an error that the makePaymentTxn method cannot be found.
