V2 API: Unable to create override_values for smart class parameter

Support
1

Hi All,

Im having some problems using the v2 API on foreman 1.4.2. I am trying to
add an override matcher to a smart class parameter. Everything works using
the foreman GUI but I get an error when I make this API call:

POST /api/smart_class_parameters/437/override_values (437 is the id of
the parameter)
POST DATA: {'override_value': {'match': 'environment=development',
'value': 'mynewval'}}

I have also tried sending this data as per the documentation:

{
"override_value": {
"match": "xyz=10",
"value": "string"
}}

But the same error occurs:

"error": {"message":"undefined method `match' for nil:NilClass"}
Any ideas? Is this a bug? I'm updating other objects using the API without any problems.

Thanks
Jeff

Ah, that fixed it. Thanks

I think you get this error if the parameters aren't found in the
request, so my guess is that you're missing the "Content-Type:
application/json" header.
