4I'm having an issue with Google Maps Directions API when using it through Power Automate's HTTP action. The problem only occurs in my sandbox environment - it works fine in development environment.
The Setup
Using Google Maps Directions API endpoint:
https://maps.googleapis.com/maps/api/directions/json
With these query parameters:
origin=Sydney Opera House, Sydney NSW, Australia
destination=Surfers Paradise, Gold Coast QLD, Australia
waypoints=optimize:true|Blue Mountains National Park, NSW, Australia|Hunter Valley, NSW, Australia|Byron Bay, NSW, Australia
key=YOUR_API_KEY
The Problem
When I include the pipe character "|" in the waypoints parameter, I get this error in Power Automate:
{
"body": {
"title": "Proxy execute request error",
"status": 400,
"detail": "ms-plex-targetServiceUrl header must be a valid Absolute Uri.",
"instance": "/extension/proxy",
"serviceRequestId": "3572fbb2-4cc2-4e54-9a07-4c87363596a4",
"exceptionSource": "InvalidProxyExecuteRequestException"
}
}
What I've Tried
- encodeUriComponent() - Error goes away but waypoints aren't recognized correctly
- Manual encoding - Replaced "|" with %7C, same result as above
- Environment testing - Works fine in development environment, only fails in sandbox (haven't tested in production yet)
Questions
- Why does this only happen in sandbox environment but not development?
- Has anyone experienced this in production environments as well?
- What's the correct way to handle pipe characters in Power Automate HTTP requests for Google Maps API?
- Is there a workaround that preserves the waypoint functionality while avoiding the proxy error?
Any help would be greatly appreciated!
