Modeler: project point (cartesian) does not accept an output from algorithm "snap geometry to layer"

[MMR100]

I want to snap points which are near lines and then move them along these lines.
In the graphical modeler, here are the step:

1. I first used "align point to feature" to know the angle of my nearest line
2. Then I use "snap geometries to layer" to snap the points to the nearest line
3. Then I use "project point (cartesian)" to move them along the line, with the angle calculated in step 1.

In step 3, the output from step 2 is not available in the list of algorithm outputs.
As a workaround I created an intermediate step between 2 and 3, such as "rename field", then I select the output of this intermediate step and it works.

@MMR100 is this a question? a bug report? else?

[MMR100]

@gioman It is a bug.
It should be possible to select "snap to geometry layer" output in the list of algorithm outputs proposed by "project point" algorithm.

@MMR100 So I guess that it works not in the context of the modeller, correct?

You are correct. The issue occurs only when using the modeller.

I'm pretty sure this is because project point exclusively accepts point data and the other tool outputs a vector layer. As the constraint is not guaranteed this is not permitted. I don't think its a bug, though the input could be made less strict and fail on execution.

Though in 3.12 it seemed fine to accept the input.

@roya0045 so regression?

[roya0045]

No sure, I can't test anything more recent right now, you can validate with a simple model (2 vectorlayer input, going in snap, then to project point).
