I am modifying an existing .module file. I noticed I was getting an Undefined Variable notice for the $ context variable that was occuring in the hook_render() hook, eg:

function my_module_render($  conf) {   $  block->content = [     '#theme' => 'my_module_panel',     '#title' => $  conf['override_title'] ? ctools_context_keyword_substitute($  conf['override_title_text'], array(), $  context) : NULL,     '#title_tag' => $  conf['override_title_heading'],   ]; } 

I tried removing it but this then Errored out the page (blank page, no noticed by error in the title).

I then tried adding the var to the function it’s self eg function my_module_render($ conf, $ context) { but got the same error.

Would anyone know what I could do here?
