Flow.RUN() failed error "TriggerInputSchemaMismatch". Error type : "Expected Number but got String"

Hi,

 

I am trying to run a flow (Execute SQL Stored Procedure) where the flow takes a GroupID from varRecord (Gallery.Selected) and an Individual ID from ComboBox.Selected.ID.

 

I am not able to fetch the GroupID using varRecord.GroupID. It comes up as blank. When I do a LookUp with the table where the GroupID is stored, it gives me a schema mismatch error. It says expected number but got string.

 

I tried using Value(LookUp(...)), but that didn't help either.

 

I am running the SP on the 'OnSelect' property of the ComboBox. The error pops up on PowerApps even before the Flow can run.

    I suspect that the GroupId property of varRecord is being read as a string when you need an integer.  Try replacing your use of varRecord.GroupId in the Lookup with value(varRecord.GroupId), rather than putting the Value() outside the lookup.

    Is the error coming from the Lookup(), if so, maybe it has to with the condition in the lookup. What is the lookup formula?

    Now I get an error as follows:

     

    'Execute Procedure V2' requires the property 'parameter/id' to be a string of maximum length '-1' but is of length '1'. error in powerapps

    LookUp(IMTable, IM_No = Gallery.Selected.IM_No).GroupID

     

    IMTable has GroupID against every IM_No

     

    Data type of IM_No and GroupID is int.

    Can you try this and see if the lookup will return a value instead of an error.

     

    LookUp(IMTable, IM_No = Value(Gallery.Selected.IM_No)).GroupID
