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.

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

```

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

```

## Error:

```auto

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,

```auto
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,

```auto

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

```

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

```auto
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.
