"Not enough liquidity to send this payment"
I'm building a web app where users can send me IOU tokens that I created. I'm testing it on the mainnet and every wallet I use to send the token gives the error "Not enough liquidity to send this payment". I'm trying to send 1 token and have confirmed the sending wallets has several tokens. I have not seen this on the testnet. What am I missing? Is there any way around this?
