Bug in chart calls which break down by specific tags

[pwsiegel]

Consider a call of the form

BWQueries().get_chart(name='My Query', startDate='YYYY-MM-DD', x_axis='days', y_axis='volume', breakdown_by='tags', dim2Args=['first_tag, 'second_tag'])

The SDK makes a call which looks like:

https://api.brandwatch.com/projects/<project id>/data/volume/days/tags?queryId=<query id>&startDate=YYYY-MM-DD&endDate=YYYY-MM-DD&dim2Args=<tag id>&dim2Args=<tag id>&access_token=<token>

But this returns a response with all data and values fields empty. The reason is that the API expects tag names instead of tag id's; the following call gives the desired result:

https://api.brandwatch.com/projects/<project id>/data/volume/days/tags?queryId=<query id>&startDate=YYYY-MM-DD&endDate=YYYY-MM-DD&dim2Args=first_tag&dim2Args=second_tag&access_token=<token>

I think the same issue came up when formulating get_mentions requests with tag filters; for some mysterious reason the API expects category ID's but tag names. 🤷‍♂️
