From the barely legible error, it looks like there is no Grease Pencil stroke associated with this object.

Got a .blend for us that shows the problem?

yes, try this .blend although the problem also appears with a new .blend file
I use google translate{F6954713}

Also if you open a new file and press gstrech you will see what the bug does.
The tool is malfunctioning in general.

From what I can tell, grease_pencil was in object or scene in 2.79.
The addon used the objects grease_pencil to stretch the vertices.
Now grease_pencil is a separate object.
The error is exactly that, object has no grease_pencil anymore.
Not sure how the annotation work. Must be in scene?

The addon needs to be updated for 2.80.
The default cube is enough for the error.

Will confirm for now, not sure yet how to convert this feature to 2.8, needs some thinking [since gpencil is indeed a separate object in 2.8]

hi, I've been looking here: https://docs.blender.org/api/blender2.8/bpy.ops.gpencil.html

64		-     gp = object.grease_pencil
	64	+     gp = bpy.data.grease_pencils
65	65	      if not gp:
66		-         gp = context.scene.grease_pencil
	66	+         gp = context.view_layers.grease_pencils
67	67	      return gp

This led to an error here:

2844		-     layer = gp.layers.active
	2844	+     layer = context.active_gpencil_layer

which led to errors in:

2845	2846	      if not layer:

this was to do with

frame = layer.active_frame

@lichtwerk I'm just guessing and stuck on frame atm. maybe on the right track?

Committed 934b32af8e although it only part fixes the issue.
Using the default cube I needed to subdivide an edge at least once for it to run in Spread modes.
Project function not working.
@cwolf3d and @antoniov are helping with the issue.

LoopTools: Gstretch fix. Grease pencil must have name 'GPencil'. Script take only the first strokes.
