"TypeError: Object of type Content is not JSON serializable"

[john0017]

`sg = sendgrid.SendGridAPIClient(api_key=API_KEY)

from_email = Email("xzy@abc.com") to_email = To("fgh@abc.com") subject = "Sending with SendGrid is Fun" content = Content("text/plain", "hi")

attachment = Attachment() attachment.file_content = FileContent(csv) attachment.file_type = FileType('text/csv') attachment.file_name = FileName('test.csv') attachment.disposition = Disposition('attachment')

mail = Mail(from_email, to_email, subject, content) mail.attachment = attachment

response = sg.client.mail.send.post(request_body=mail.get()) `print(response.status_code)``

The csv above is a pandas df converted to csv and then encoded.

The code works fine on jupyter notebook, however on VScode/ Pycharm i get the error "TypeError: Object of type Content is not JSON serializable"

Hi,

Any thoughts on this?

How is the variable csv being defined?

How is the variable csv being defined?

Thank you for your response. The code works fine on jupiter notebook but not on Pycharm or VS code.

The csv file is defined as -

with open('filename.csv', 'rb') as f: data = f.read() csv = base64.b64encode(data).decode()

hi, any update?

Hi @john0017, Can you update to the latest version of the sendgrid-python library v6.8.1 and try re-running your code to see if you still see the JSON serializable error?

Thank you for your response. However, that did not work either. I updated the script by not using the Mail helper class and that seems to work.
