OutputTooSmallUTxO error

Question

I'm following these steps and I get the OutputTooSmallUTxO error. Not sure what I missed from the steps but here's my parameters and the error as a whole.

tokenname1="Testtoken" tokenname2="SecondTesttoken" tokenamount="100000000" output="0"

fee="300000" txhash="8a7e45c02cf25cb1b9870fbcc87b61d61cefb514ccfb960bcc7651023ea7ffb2" txix="0" funds="1000000000" policyid=$(cat policy/policyID)

cardano-cli transaction build-raw
--fee $fee
--tx-in "$txhash#$txix"
--tx-out $address+$output+"$tokenamount $policyid.$tokenname1 + $tokenamount $policyid.$tokenname2"
--mint="$tokenamount $policyid.$tokenname1 + $tokenamount $policyid.$tokenname2"
--minting-script-file policy/policy.script
--out-file matx.raw

fee=$(cardano-cli transaction calculate-min-fee --tx-body-file matx.raw --tx-in-count 1 --tx-out-count 1 --witness-count 1 --testnet-magic 1097911063 --protocol-params-file protocol.json | cut -d " " -f1) (This was not incluted in the tutorial and i added it from a block post i found here in reference to a similar issue)

Answer 1

Looks like you don't account for change return value (your $output variable which is zero).

Your transaction spends some UTxO to pay the fee but the rest of this UTxOs ADA has to go somewhere (hence the value not conserved error).

I think you need to look up the ADA value of the --tx-in "$txhash#$txix" (your $funds variable?) and subtract fee from it, which is the unspent ADA you get back.
