400 - Invalid Query Error for Production Index

Hello,

I have recently taken over a project that has searchkick implemented to sift through "Questionnaire" objects. However, when I enter a search term, I receive a 500 from nginx. Looking closer into Puma logs, I find the following:

Searchkick::InvalidQueryError ([400] {"error":{"root_cause":[{"type":"query_shard_exception","reason":"[match] analyzer [searchkick_search] not found","index_uuid":"Vtd4-LgVQiqmA-W0uiDSzw","index":"questionnaires_production"}],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[{"shard":0,"index":"questionnaires_production","node":"Oto8Jh7CQt6Qtsmz9jU6AA","reason":{"type":"query_shard_exception","reason":"[match] analyzer [searchkick_search] not found","index_uuid":"Vtd4-LgVQiqmA-W0uiDSzw","index":"questionnaires_production"}}]},"status":400}):
  app/controllers/questionnaires_controller.rb:30:in `index'

I have tried rake searchkick:reindex:all, rake searchkick:reindex CLASS=Questionnaire, and Questionnaire.reindex in the rails console. Running the first two commands results in the "reindex complete" message.

The tool successfully indexes the content in the database "compliance_reports_development", but not the data in "compliance_reports_production". Is there some configuration I might be missing that would cause this?

Below is my Gemfile:
