EikonError: Error code 413 Client Error: Request Entity Too Large - get symbology

I looked up a similar question to mine on the developer community, and the best solution proposed was dividing the list of symbols into 100. Is there a more efficient way to get rid of this error?

I am trying to use "get_symbology" to get RIC codes based on a list of 9200 ISINs.

My code and the full error below:

RICs, err= ek.get_symbology(list(ISIN_List), from_symbol_type="ISIN", to_symbol_type= "RIC")

RICs

    Hi @Erik77 - thanks for your question. Yes an instrument list of 9200 ISINs will be too large for the API to handle at once. Please be aware of the data limits of the APIs by looking at the document here. You can try chunking the list into smaller pieces (lets say 100 ISINs) and presenting each chunk to the API. You need to pip install pydash first. You can chunk your list using:

    from pydash.arrays import chunk
    chunklist = chunk(ISIN_list, 100)
    chunklist

    and then present each chunk of 100 ISINs to the API.

    I hope this can help
