Invalid Parameter error on create_template function, Buttons section
Describe the bug
When calling:
from pywa.types import NewTemplate as NewTemp
wa.create_template(
template=NewTemp(
name='buy_new_iphone_x_with_buttons',
category=NewTemp.Category.MARKETING,
language=NewTemp.Language.ENGLISH_US,
header=NewTemp.Text('The New iPhone {15} is here!'),
body=NewTemp.Body('Buy now and use the code {WA_IPHONE_15} to get {15%} off!'),
footer=NewTemp.Footer('Powered by PyWa'),
buttons=[
NewTemp.UrlButton(title='Buy Now', url='https://example.com/shop/{iphone15}'),
NewTemp.QuickReplyButton('Unsubscribe from marketing messages'),
],
),
waba_id=MY_WABA_ID
)
I'm getting this error:
2025-01-22 14:22:14,457 - httpx - INFO - HTTP Request: POST https://graph.facebook.com/v21.0/335760796291207/message_templates "HTTP/1.1 400 Bad Request"

Hi,
One thing you could do to try to get a bit more information is to run it using a post request:
ie
endpoint = f'https://graph.facebook.com/v22.0/{waba_id}/message_templates'
headers = {
'Content-Type': 'application/json',
'Authorization': f"Bearer {os.environ['TOKEN']}"
}
resp = requests.post(endpoint, headers=headers, json=carousel)
print(resp.json())
When having a similar problem I found this error message to provide a lot more detail, and helped identify the problem:
{'error': {'message': 'Invalid parameter',
'type': 'OAuthException',
'code': 100,
'error_subcode': 2388043,
'is_transient': False,
'error_user_title': 'Message template "components" param is missing expected field(s)',
'error_user_msg': 'component of type HEADER is missing expected field(s) (example)',
'fbtrace_id': '...'}}
It looks like the PyWa WhatsAppError exception only pulls out the message from the error, which in this particular case is not that informative.
I see. About the problem itself, I'll need to check it first. And about the WhatsAppError, I see what you mean. I'll try to think on something, but in the meantime you can access the raw response from the exception. I think it's the raw_response attr. The httpx response.

Still got the same problem while creating template (video+body) template { "error": { "message": "Invalid parameter", "type": "OAuthException", "code": 100, "error_subcode": 2388043, "is_transient": false, "error_user_title": "Message template "components" param is missing expected field(s)", "error_user_msg": "component of type BODY is missing expected field(s) (example)", "fbtrace_id": "v7lcM1EEramdsCVemxJKDOD" } }
