Error when Updating Campaign Content

[rachaellynn]

I've been running this script for a few months now, off and on, and just started getting this error when updating campaign content with a template id. The campaign and the template do exist. Please advise! Thanks.

client.campaigns.content.update(campaign_id=campaign_id, data={'template':{'id':template_id}}) #170519 having trouble with this one

Sorry for the long delay, are you able to get the campaign itself using the id in the campaigns.get() method, and are you able to get the template with templates.get()? I see that you are obviously providing a value for the campaign_id, could you provide the context around that line on where you are getting the template_id that is being used?
