L4 Error - LLAMA_CLOUD_BASE_URL undefined

I tried to run Lesson 4: Form Parsing in my local instance and was unable to get it to work. It appears that the LLAMA_CLOUD_BASE_URL environment variable being referenced is not defined. I tried setting it to http://jupyter-api-proxy.internal.dlai/rev-proxy/llama-cloud, but still got errors. Any idea what the issue is? Here are the errors after running cell 5.

WARNING: content_guideline_instruction is deprecated and may be remove in a future release. Use system_prompt, system_prompt_append or user_prompt instead.

Hi, I commented the code line below and it worked fine:
#base_url=os.getenv(“LLAMA_CLOUD_BASE_URL”)

On a related note, in the same function call, I replaced “content_guideline_instruction” with “system_prompt” and it worked just fine.
i.e., I replaced this
content_guideline_instruction=“This is a job application form. Create a list of all the fields that need to be filled in.”,

with:
system_prompt=“This is a job application form. Create a list of all the fields that need to be filled in.”,

HTH!
