We met an exception in spdlog:

[*** LOG ERROR #0001 ***] [2021-09-26 13:59:46] [Speck2bMiniTestboard] {cannot switch from manual to automatic argument indexing}

it is caused by the wrong msg format:

logger.debug("WriteRegisterValue addr: {0:x}, bias: {}", arg.address, arg.data);

which should be :

logger.debug("WriteRegisterValue addr: {:x}, bias: {}", arg.address, arg.data);

But the exception msg is too simple , it doesn't notice us about the origin msg. so it's hard to locate , can you improve the exception msg ?
