Trying to send axlUSDC from Osmosis to Kujira, but when want to pay for the fee using Keplr wallet, the transactions fails and gives the message:
Invalid string. Length must be a multiple of 4.
This is a known issue, but users have reported that if you manually increase the gas, the transfer will still go through, even with that warning.
In addition, if that doesn't help, please try to do the same via https://app.squidrouter.com
