Unexpected Formula error in flow (QnA maker flow)

[RahulSiddharth]

Powerapps throws the formula error (expected operator) while using the flow function (Bot.run, where bot is the name of the flow)
It is not accepting the Knowledge base ID and shows syntax error. PFB the attached screenshot. The flow is working normally when tested in portal. 

Suggest a solution or work around.

Hi @RahulSiddharth ,

If the Knowledge base ID field requires the GUID, please try to converts a GUID string to a GUID value via GUID() function.

Collect(chat, Bot.Run(GUID("...."), TextInput1.Text)

 Hope this helps.
