I have been running a scenario for some time that simply gets an email address from a Stripe payment and adds it to a SendGrid list. Just yesterday, I began getting the following message:
[400] Error on field : invalid input
I only have the email field from Stripe in the scenario and I’ve verified the format of the email is fine.
I’m having the same problem here, and have tried in vain to add and re-add the Sendgrid module, and tested it. Same basic scenario, just adding a purchaser to a list in order to run an automation in Sendgrid. It’s broken. We have 50 different campaigns that are directly effected by this.
I’m facing the same issue. Just trying to add an email to a SendGrid list using “Add or Update a Contact (New)” in Make, but receive [400] Error on field : invalid input. Outbound bundles are null.
