Hi,
I’m trying to update a doctype value via the FrappeClient Python API. Getting a value works fine. However, when I try to update a value I get an error. I followed the steps described on GitHub - frappe/frappe-client: Python library to use Frappe API
My code:
from frappeclient import FrappeClient
client = FrappeClient(“https://example.com”)
client.authenticate(“my_api_key”, “my_api_secret”)
doc = client.get_doc(‘Item’, ‘Aluminium’)
print(doc[‘valuation_rate’])
doc[‘valuation_rate’] = 1.8
client.update(doc)
The response:
1.6
Traceback (most recent call last):
File “d:\Work\Internal\ERPNextAPI.py”, line 35, in
client.update(doc)
File “c:\users\ricka\frappe-client\frappeclient\frappeclient.py”, line 116, in update
return self.post_process(res)
File “c:\users\ricka\frappe-client\frappeclient\frappeclient.py”, line 285, in post_process
raise FrappeException(rjson[‘exc’])

Does anybody know what I’m doing wrong and how to solve this?
Thanks
