Getting random empty lists back with listMarketBook

[JayBee]

I have a routine that cycles through all of today's races and performs a listMarketBook with their marketIds.

Occasionally, certain races do not return a result list of prices. Even if I hard code the marketId into the program, nothing is returned.

I know the request is correct because I get data back for other races.

I know the marketId is correct because I can plug it into the Visualiser and get the data.

Has anyone else had this problem?

Yes - I get the same every now and then.

I just trap it and re-request the prices.
