SyntaxError("not a PNG file") #72

Closed erickalfaro closed 1 year ago

Hi all,

As of last night at around ~5:51PM EST this function call no longer works for me.

dfi.export(styled, '../../data/images/trending.png')

I have a process that runs every minute. It has been running for over a year now.

I am seeing chatter around others having the same issue.
