Unexpected JSON response from AlphaVantage

[Ezyweb-uk]

Using the code in your example with my API-Key I get the following error:

Fatal error: Uncaught FastStockQuotes\Exceptions\UnexpectedAPIResponseException: Unexpected JSON response from AlphaVantage API - they may have changed. Please contact author Response: {} in D:\www\stockquotes\src\QuoteAPIs\AlphaVantageRequestHandler.php:111 Stack trace: #0 D:\www\stockquotes\src\QuoteServiceImpl.php(115): FastStockQuotes\QuoteAPIs\AlphaVantageRequestHandler->quoteFromResponse('{}') #1 D:\www\stockquotes\src\QuoteServiceImpl.php(67): FastStockQuotes\QuoteServiceImpl->_quotes(Array, Array) #2 D:\www\stockquotes\src\QuoteServiceCached.php(55): FastStockQuotes\QuoteServiceImpl->quotes(Array) #3 D:\www\stockquotes\test.php(24): FastStockQuotes\QuoteServiceCached->quotes(Array) #4 {main} Next FastStockQuotes\Exceptions\FastStockQuotesException: Error retrieving stock quote(s) for: "WBC.AX" Cause: Unexpected JSON response from AlphaVantage API - they may have changed.

I've checked my API-key works.
