Problem/Motivation
I am not sure, if this issue is related to Commerce Promotion or Drupal Core. The error is pointing to Drupal core options.module. Just a note this website, is migrated from Drupal 7. and I am using Commerce version 3.
It seems, while showing promotion list, the function expect a string but got an array. When I debug, it shows this:
array:2 [▼
0 => "Drupal\commerce_promotion\Entity\Promotion"
1 => "getOfferOptions"
]
Steps to reproduce
When I tried to visit the url "/admin/commerce/promotions", the page breaks and show the error with this detail:
TypeError: function_exists(): Argument #1 ($function) must be of type string, array given in function_exists() (line 90 of core\modules\options\options.module).

Proposed resolution
We might check, if $function is an array or string. If string, we can call directly otherwise call the function inside the class
