Extra resources fails when using selector on field generated by previous step

[JakobGSvendsen]

What happened?

I am trying to use a value from a extra resource to find another extra resource.
Since I couldnt find a way to map it inside one instance of the function in a pipeline, I decided to make a "predeploy" template step that simply reads the value and outputs to "status".

Then after that step I want to run a second extra resroucce step that uses the status value to get the additional extra resource, but it fails.

I thought it worked, but it turned out it only worked cause I updated it on already existing resources that did already have the status set.

For new resource I get:

message: 'cannot compose resources: pipeline step "pull-extra-resources-identity" returned a fatal result: could not build extra resource requirements: cannot get value from field path "status.iitech.shortName": status.iitech: no such field'

Is it not possible to make it like this? I thought it would be as it is a "pipeline".
if not, is there any other way that I can use a value from my "blueprint" extra resource to find my "userassignedIdentity" resource?

How can we reproduce it?

This is my composition, the field I am setting is defined in the compositeresourcedefintion:

What environment did it happen in?
