Initial indexing crashes with TypeError

[WetenSchaap]

Issue Description

When I try to perform the initial indexing using ./plugin.php elasticsearch index, I get the following error:

☠ TypeError: array_change_key_case(): Argument #1 ($array) must be of type array, string given in /app/www/public/inc/auth.php:192
Stack trace:
#0 /app/www/public/inc/auth.php(192): array_change_key_case()
#1 /app/www/public/inc/auth.php(98): auth_tokenlogin()
#2 /config/dokuwiki/lib/plugins/elasticsearch/cli.php(67): auth_setup()
#3 /app/www/public/vendor/splitbrain/php-cli/src/Base.php(217): cli_plugin_elasticsearch->main()
#4 /app/www/public/vendor/splitbrain/php-cli/src/Base.php(145): splitbrain\phpcli\Base->execute()
#5 /app/www/public/bin/plugin.php(45): splitbrain\phpcli\Base->run()
#6 /app/www/public/vendor/splitbrain/php-cli/src/Base.php(217): PluginCLI->main()
#7 /app/www/public/vendor/splitbrain/php-cli/src/Base.php(145): splitbrain\phpcli\Base->execute()
#8 /app/www/public/bin/plugin.php(110): splitbrain\phpcli\Base->run()
#9 {main}

I am not entirely sure what is going wrong, and whether I am responsible somehow - but the result is that indexing does not work. Search results are always empty.

We run Dokuwiki using the Linuxserver docker image, if that matters.

Seems to be similar to cosmocode/dokuwiki-plugin-aichat#17

I'm getting the same error too on Kaos, info that was requested in cosmocode/dokuwiki-plugin-aichat#17:

I'm running this in a Docker container using FROM php:8.4-apache-bookworm

Edit:
Unrelated to this issue, I don't think php:8.4-apache-bookworm works well with Dokuwiki - I get the following when I try to load any page:

When I downgrade to php 8.3 or 8.2, I get the same results though (same error, so I removed that from the output):
