Problem

Sending IPAWS messages in Everbridge Suite generates the error:

Invalid Polygons

Root Cause

Shapes included in IPAWS messages are exceeding geopoint limits.

Solution

Send IPAWS messages with shapes that do not exceed the limitations listed below:

• For the Wireless Emergency Alerts (WEA) channel, shapes must have less than 100 geopoints.
• For the Emergency Alert System (EAS) and Non-Weather Emergency Message (NWEM) channels, shapes must have less than 200 geo-points.

For better control over the amount of points a shape has, create a polygon on the Everbridge map. See knowledge article EBS: Using Shapes to Select Contacts for a Notification in Everbridge Suite for information on creating a polygon.
