Error while building transaction (--tx-out: unexpected 'n' expecting alphanumeric asset name, white space, "+" or end of input)

I was following this tutorial about minting nfts and when I entered this command to build the transaction: cardano-cli transaction build \

--mainnet \

--alonzo-era \

--tx-in 32b522ab6f403cf5032d4aed87673298ef5ef4f4af774b38307d2bf3fa645131#0 \

--tx-out $address+$output+"$tokenamount $policyid.$tokenname" \

--change-address $address \

--mint="$tokenamount $policyid.$tokenname" \

--minting-script-file $script \

--metadata-json-file metadata.json \

--invalid-hereafter $slotnumber \

--witness-override 2 \

--out-file matx.raw

I got this error back: `–tx-out:
unexpected ‘n’
expecting alphanumeric asset name, white space, “+” or end of input

`

Any ideas on how to solve this? You can find the tutorial here->(Minting NFTs | Cardano Developer Portal)

Hi!,
My recomentation is don forget define variables as

tokenname1=“Testtoken”
tokenamount=“10000000”
output=“0”

export CARDANO_NODE_SOCKET_PATH="$HOME/TESTNET_NODE/socket/node.socket"

and add the variables related to libsodium
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"
