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/](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/](https://www.google.com/)”,  
“base\_url”: “[https://sim-india-prod-iothub.azure-devices.net](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?
