In a nutshell: importing to a container tree (>= 2 levels) doesn't work
nothing imported when not required metadata
error message that have little to do with the problem
Here's the mapping file again, just in case.
Any help would be really appreciated ! I'm quite stucked on that one.
I'm unsure whether you can pass constants into the refinery - from memory I've had mixed results here. A workaround I've used is to map any field value, and then add a `template` in the settings explicitly setting the value to the value you want the refinery to lookup. Alternatively just use the idno of the list item you want as the constant and don't use the refinery.
Additionally if you're mapping into a container, you only need to include the topmost container and then the final destination field, so instead of:
as the destination.
You cannot pass constant into refineries at present. They're only used for explicit mappings. Probably should make them into proper values.
