Can't send FlexMessage with Hero block #273
Description
System Informations
- Python version: 3.7.7
- SDK version: 1.16.0
- OS: macOS Mojave 10.14.3
Expected Behavior
The docs say that box or image can be used for hero block.
https://developers.line.biz/en/reference/messaging-api/#bubble
Hero block. Specify a box or an image.
Current Behavior
I tried to send FlexMessage with box block, but got an error.
e.status_code: 400
e.error.message: A message (messages[0]) in the request body is invalid
e.error.details: [{"message": "must be specified", "property": "/hero/url"}]
Hero seems to be initialized with ImageComponent if I pass in a json.
Probably this question also has the same error.
