Connection 'AzureAISearch' required for flow 'copilot_promptflow' is not found.

Just followed the readme. Created the search index. Made sure the .env contains keys, etc related to azure search. Also made sure the yaml in contains the search index:
- name: retrieve_documentation
type: python
source:
type: code
path: retrieve_documentation.py
inputs:
search: AzureAISearch
question: ${inputs.question}
index_name: product-info
embedding: ${question_embedding.output}
**However, running the command for prompt flow "python src/run.py --implementation promptflow --question "what is the waterproof rating of the tent I just ordered?"" I kept receiving the following error on both my local machine and code space:**
python src/run.py --implementation promptflow --question "what is the waterproof rating of the tent I just ordered?"
