Native serialization error

[Geir V. Berglind]

Hi!

Having finished porting a orderacknowledgement from
Bt2002, I get the following error: Native serialization
error: Value cannot be null. Parameter name: format.

I have no idea where to start looking. The input schema
validates ok (instance), the mapping validation is ok but
when I try instance validation of the mapping (the same
as used in the input schema), I get the error.

Help,
Geir

I had this issue. In my case it disappeared if I tested the map using xml output instead of native output. I checked the xml output and found the map was generating duplicate fields. This could not be serialized into the flat file schema and that was the cause of the error.
