Application Webhooks Post not working - giving error for base URL

Application Development
1

I am using Application Webhook API to create a webhook for application. After I followed the following documentation, I am getting error for base_url attribute.

Documentation I followed -
https://www.thethingsindustries.com/docs/reference/api/application_webhooks/

I tried different URLs but getting same error everytime. Here are few URLs
“base_url”: “https://www.google.com/”,
“base_url”: “https://sim-india-prod-iothub.azure-devices.net”,

Error response -
“field”: “base_url”,
“name”: “ApplicationWebhookValidationError”,
“reason”: “value must be absolute”

Can someone help with this issue?
