Can faucet() accidentally create more than one utxo?

One every 20 times I get random errors in my integration tests using regtest-client.

I create some utxos and then I retrieve them from the blockchain and verify they were created before proceeding with more complex tests.

In fact, I do something like what you do here (except I sum all the funds that can be spent by that address and compare to the funds theoretically sent there):

regtest-client/test/index.js

Line 41 in d4cd262

assert.deepStrictEqual(

But from time to time I end up having 2 utxos that can be spent with the same address. It's kind of random.

Coincidentally, I have also randomly seen this warning/error on my logs:

regtest-client/src/index.js

Line 124 in d4cd262

console.log('Missing Inputs, retry #' + count);

I cannot conclude these are related because these random errors are very rare.

Also, I'm not 100% sure about what these "retrials" mean.

Can it be the case that faucet() may produce a new utxo because it did not detect the previous one as done?
