Describe the bug

In my smart contract, there's a function defined as follows:
function playTicket(uint8[6] memory) external payable;

I'm attempting to invoke this function by sending a fixed-sized array of uint8 numbers (1 to 6) using the following cast send command:
cast send ${CONTRACT} "playTicket(uint8[6])" "[1,2,3,4,5,6]" --rpc-url ${RPC} --private-key ${PRIVATE} --value 0.02ether

However, I'm encountering a type mismatch issue with the error message:
type mismatch: expected type "uint8[6]", got value with type "uint8[]"

Despite searching the documentation, I'm unable to resolve this problem. Any guidance on how to address this issue would be greatly appreciated.
