When I input terms to the search form, it redirect to index.php.
<?php bbp_get_template_part( 'form', 'search' ); ?>

I went through troubleshooting here and changed search slag to ‘find’ but it couldn’t resolve.

Search Redirects to Front Page

I also tried common troubleshooting here: https://codex.bbpress.org/getting-started/troubleshooting/
Nothing changed.

It seems my customized theme causing an issue because it worked when I switched to the default ‘Twenty Nineteen’ theme it worked.
But I have no idea which part is causing the issue. Can somebody help?
