Hi,
I'm using BO 4.0 SP5 and have problem.
In some report when I schedule it I'm getting erro:
An internal error occured while calling 'getPages' API. (Error: ERR_WIS_30270)
It's happened only in few reports. What is strange that after this error I schedule one more time and after few sucsessed executio I'm getting the same error 
When I refrereh manual this report in BI LauchPad I don't get error.
