Are you sure that you have *exactly* the same issue? Two independent
problems are actually involved here.

This error happens when you are using an old version of Bash. If you
have correctly set up a recent version of Bash for the user's default
login shell or for the shell started by kitty, this error for "-A"
should vanish.

FYI, this is caused by the following line [1] of kitty's
shell-integration script, which is released in kitty-0.24.2 just 21
days ago [2]:

> builtin declare -A _ksi_prompt

This is an independent problem from the previous one and happens
regardless of the version of Bash you are using. This is a bug in
kitty's shell-integration script [3] and already fixed in the nightly
build of kitty [4]. The fix has not yet released.

----------
By the way, the latest version of kitty's shell-integration script
still seems to have a bug in this line [5]. With this, PROMPT_COMMANDs
specified to other array elements will be lost when PROMPT_COMMAND[0]
is empty. This situation (where the PROMPT_COMMAND[0] is empty and
there are other non-empty elements) is common when one uses the trick
suggested by Martijn Dekker [6]. In fact, my script would be affected
by this version of kitty's shell-integration script...
