Recently, I’ve seen a big uptick in the value Invalid date showing up in user records for the attribute CREATED_AT . For some of my records though, a valid date format and value appear.
We send data into Customer.io via Segment.io. When we set it up, we mapped the following:
traits.created_at » CREATED_AT
And it worked fine until recently.
I read this Customer.io FAQ that discusses how to know if the proper date format (epoch) is coming in or not, and for my recent records, it is not.
Has anyone else seen this? Does anyone have a solution they can offer up for me to try?
Here’s a screenshot showing when users were created yet they have invalid and invalid date values.
Thank you,
Mike
