numpy - Python - TypeError: Object of type 'int64' is not JSON serializable

Question

I have a data frame that stores store name and daily sales count. I am trying to insert this to Salesforce using the Python script below.

However, I get the following error:

TypeError: Object of type 'int64' is not JSON serializable

Below, there is the view of the data frame.

Storename,Count
Store A,10
Store B,12
Store C,5

I use the following code to insert it to Salesforce.

update_list = []
for i in range(len(store)):
    update_data = {
        'name': store['entity_name'].iloc[i],
        'count__c': store['count'].iloc[i] 
    }
    update_list.append(update_data)

sf_data_cursor = sf_datapull.salesforce_login()
sf_data_cursor.bulk.Account.update(update_list)

I get the error when the last line above gets executed.

How do I fix this?

Answer 1

json does not recognize NumPy data types. Convert the number to a Python int before serializing the object:

'count__c': int(store['count'].iloc[i])
