Originally created by @ggjx22 on GitHub (Apr 23, 2024).

Recently, I am running into RuntimeError while using LlamaParse.
This is my job id: job_id ee9624b6-9a4a-4b4c-8229-05735fe807a2
Has anyone encounter the same and know what exactly is going on?

@ggjx22 how did you call llama-parse? Can you give some code?

And also, what version are you on? I would try updating pip install -U llama_parse

I am reading the .pdf files directly from azure blob storage.

def get_file_extractor(llama_cloud_api_key):
    # instantiate the parser
    parser = LlamaParse(
        api_key=llama_cloud_api_key,
        result_type='markdown',
        parsing_instruction=get_parser_instructions()
    )
    
    file_extractor = {'.pdf': parser}
    
    return file_extractor
    

def get_azure_blob_reader(container_name, container_blob_name, connection_string, blob_name, file_extractor):
    return AzStorageBlobReader(
        container_name=f'{container_name}/{container_blob_name}',
        connection_string=connection_string,
        blob=blob_name,
        file_extractor=file_extractor
    )
    

def parse_file_from_az_blob(container_name, container_blob_name, connection_string, blob_name):
    # create file extractor
    file_extractor = get_file_extractor(llama_cloud_api_key=LLAMA_CLOUD_API_KEY)
    
    # get the azure blob reader
    az_blob_reader = get_azure_blob_reader(
        container_name=container_name,
        container_blob_name=container_blob_name,
        connection_string=connection_string,
        blob_name=blob_name,
        file_extractor=file_extractor
    )
    
    # load data from blob
    try:
        document = az_blob_reader.load_data()
        return document
    
    except Exception as error:
        print(f'ERROR: An error has occured while parsing the file. {error}')

This is how I am calling the functions:

document = llama.parse_file_from_az_blob(
    container_name=storage_container_name,
    container_blob_name=container_blob_name,
    connection_string=connection_string,
    blob_name=blob_name
)

I am on version 0.4.1 but the RuntimeError is still happening. My latest parsing job id that is causing the error is job_id a943c84f-4d98-4ec5-aa8a-794c031a4c37

I have a feeling its maybe failing to load from azure, and killing the async loop

Does it work if you remove the file extractor?

Currently I am testing with 9 pdf files in my blob storage. The RuntimeError issue does not appear if file_extractor is not provided to AzStorageReader. When LlamaParse is provided as seen in issue above, I will encounter around 2 to 3 RuntimeError in a loop.

@logan-markewich :
I am also facing the same error.
Error while parsing the file 'C:\Users\blabla\AppData\Local\Temp\tmp3ng9nl_s.pdf': Event loop is closed

As a temporary solution, creating an instance for every new request is not optimal in production set up. The library version is specified below:

llama-cloud-services==0.6.22

Any workaround to fix this error?

Thanks
