When I try to index a jason file using "es.helpers.bulk" the error "TypeError: pop expected at most 1 argument, got 2" is occurring

[pand (veera)]

When I execute the following code the error "TypeError: pop expected at most 1 argument, got 2" is occuring, please provide solutions to fix this.

def creatdocs(filename,pdfcontent):
    docs = [{
            'content': paragraph,
            'meta': {
            'source': filename
            }   
        }for paragraph in pdfcontent
    ]
    yield docs

#calling the function:
helpers.bulk(es, creatdocs(filename,pdfcontent),index='indexname2')

Error:

Welcome!

I'm not sure but it looks like the header of each line is missing...

But the following code works well, if we call the "helpers.bulk()" next to the json,

def creatdocs(filename,pdfcontent):
    docs = [{
            'content': paragraph,
            'meta': {
            'source': filename
            }   
        }for paragraph in pdfcontent
    ]
helpers.bulk(es,docs,index='statutory2')

The error occurs only if we call the "helpers.bulk()" from outside of the function.

I did some analysis on the piece of code in the "action.py"
Python 3.10.7\lib\site-packages\elasticsearch\helpers\actions.py", line 65,

op_type: str = data.pop("_op_type", "index")

Created the following two lines of code and executed which produces the same error.

data=[{"Lion","Tiger","Giraffe",'Panda'}]
op_type: str = data.pop("_op_type", "index")

I tried many possibilities but no luck, please provide your idea or solution which will help me to fix this.
