Ticker24hrService bugged

[the-potato-church]

When calling NewTicker24hrService().Symbols(symbols).Do(ctx) where symbols represents about 1000 symbols, I get the following error: <APIError> code=0, msg=. I suspect that I might be exceeding some undocumented limit on the amount of symbols that the API can process, but the erorr is rather unhelpful.

When calling NewTicker24hrService().Do(ctx) to fetch all symbol info in order to bypass any possible limits I get the following error:
json: cannot unmarshal number -1 into Go struct field Ticker24hrResponse.firstId of type uint64. I suspect this comes from trying to process a symbol which has no trades yet - and the firstId being uninitiliased.

I appreciate any help/fix. Thanks!
