Broken bash completion

[candlerb]

• Type "./pulsarctl topics de"
• Hit Tab

Result:

$ ./pulsarctl topics de-su: aliashash[""]: bad array subscript

I have the same problem on linux systems (centos 7, centos 8, debian testing) any of them doesn't work.

$ pulsarctl bash: aliashash[""]: bad array subscript
$ pulsarctl topbash: aliashash[""]: bad array subscript
$ pulsarctl topics bash: aliashash[""]: bad array subscript

A simple repro to this issue:

FROM ubuntu:24.04

RUN apt-get update && apt-get install -y curl bash-completion

RUN bash -c "$(curl -fsSL https://raw.githubusercontent.com/streamnative/pulsarctl/master/install.sh)"

RUN echo 'export PATH=${PATH}:${HOME}/.pulsarctl/plugins' >> ~/.bashrc \
        && echo "source /etc/profile.d/bash_completion.sh" >> ~/.bashrc \
        && echo ". <(pulsarctl completion bash)" >> ~/.bashrc

❯ docker run --rm -it pulsarctl:test bash
root@18000a6fb81c:/# echo $BASH_VERSION
5.2.21(1)-release
root@18000a6fb81c:/# pulsarctl combash: aliashash[""]: bad array subscript
