I have a flask app which I've deployed to Heroku, one of the routes is the following
def get_kws():
seed_kw = request.json['firstParam']
audience_max = request.json['secondParam']
interest_mining_service = InterestMiningService(seed_kw, audience_max)
query_result = interest_mining_service.query_keyword().tolist()
if seed_kw in query_result:
print ("yes")
return jsonify(
{
'keyword_data' : interest_mining_service.find_kws().to_json(orient='records'),
'query_results': query_result
}
)
When I test this endpoint locally, I have no issues when sending POST and GET requests to that endpoint. However, when I deploy to Heroku, I get the following error:
File "/app/server/controller.py", line 24, in get_kws

I've never seen this error Request object has no attribute 'is_xhr'
before and it only seems to be happening when I deploy to Heroku. Any guidance on what I should look into?
There also doesn't seem to be an issue with the json key keyword_data
- the issue seems limited to query_results
which is a list.
