Unable to serialize Option<address> in CLI PTB

[Thoralf-M]

Bug description

In the CLI it's not possible to provide an option with an address as parameter to call a move function

For example calling this function in the testnet

iota client ptb \
--assign addr "some(@0xa5657935a0698bf654ce4ceb66b5a6d6a371a934a6afcfd1e191aa2ee460c8cc)" \
--move-call 0xf5097105292df26739f5d2ca10d5011e6bc54245ef7f1e0c708de3aa7f946544::example::optional_address_param addr \
--dry-run

fails with

Encountered error when building PTB:

Could not build PTB due to previous error

Steps To reproduce the bug

1. Have a function that accepts option<address>, for example

    public fun optional_address_param(
        address_option: Option<address>,
    ): bool {
        option::is_some(&address_option)
    }

2. Try to call it in the CLI with a PTB

Since the error mentions vector<address> I also tried to provide a vector instead, but this also doesn't work:

iota client ptb \
--make-move-vec "<address>" "[@0xa5657935a0698bf654ce4ceb66b5a6d6a371a934a6afcfd1e191aa2ee460c8cc]" \
--assign addr \
--move-call 0xf5097105292df26739f5d2ca10d5011e6bc54245ef7f1e0c708de3aa7f946544::example::optional_address_param addr \
--dry-run
