I can't find an official support page or point of contact for this Google API and the contact page suggests I should post to StackOverflow so here I go.
Within the last hour or so, I've been getting this error from all of my Google KG Search requests:
{
"error": {
"code": 400,
"message": "Request contains an invalid argument.",
"status": "INVALID_ARGUMENT"
}
}
My API key is still valid and the developer's console is logging the errors. I have a handful of test commands I've put in that have worked as of last Friday. I have also used the official API explorer web interface with no such luck. (See: https://developers.google.com/apis-explorer/#search/knowledge/kgsearch/v1/kgsearch.entities.search)
Has anyone else used this API before or are currently experiencing this issue?
