// BitPosSpan supports the `byte | bit` parameters in redis version 7.0,

// which means it counts in bytes from start to end. you can set the value
// of "span" to determine the type of `start-end`.
// span = "bit", cmd: bitpos key bit start end bit
// span = "byte", cmd: bitpos key bit start end byte

Solutions

1. Pass at most the supported arguments for this bitmap command; extra positional arguments beyond key/offset/value are rejected
2. Check the command signature in the go-redis docs and trim the variadic args you build

When it happens

Trigger: Thrown at bitmap_commands.go:145 when the library encounters an invalid state.

Common situations: Validate argument counts against a fixed schema before dispatching dynamically built bitmap commands.
