A surface copied from Google maps that does not react to light

Question

I installed the Blosm plugin and copied an area from Google Maps to Blender. But the area does not respond to the light in Render Mode,and also in the final render. Even when I try to connect to it principled BSDF in Nodes. How can it be made to react like a mesh or at least copy it to another surface that reacts to light, or another creative solution?

I had this issue, code to fix it below. I'll try to keep in touch as developing on it as we speak, but be sure to remove the right indent on that second line of code. Good Luck

import bpy

for mat in bpy.data.materials:
if not mat.use_nodes:
    continue
nodes = mat.node_tree.nodes
mix = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeMixShader)), None)
while mix is not None:
    nodes.remove(mix)
    mix = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeMixShader)), None)
emission = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeEmission)), None)
while emission is not None:
    nodes.remove(emission)
    emission = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeEmission)), None)
transparent = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeBsdfTransparent)), None)
while transparent is not None:
    nodes.remove(transparent)
    transparent = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeBsdfTransparent)), None)
light_path = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeLightPath)), None)
while light_path is not None:
    nodes.remove(light_path)
    light_path = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeLightPath)), None)
output = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeOutputMaterial)), None)
if output is None:
    continue
principled = nodes.new("ShaderNodeBsdfPrincipled")
principled.location = (output.location[0] - 400, output.location[1]+100)
mat.node_tree.links.new(principled.outputs[0], output.inputs[0])
texture = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeTexImage)), None)
if texture is None:
    continue
mat.node_tree.links.new(texture.outputs['Color'], principled.inputs['Base Color'])

Adds a value node and connects it to Specular with a value of 0.5.

valueA = nodes.new("ShaderNodeValue") 
valueA.location = (principled.location[0] - 200, principled.location[1]-200)
valueA.outputs[0].default_value = 0.5
mat.node_tree.links.new(valueA.outputs[0], principled.inputs['Metallic'])

Adds a value node and connects it to Roughness with a value of 0.5.

valueB = nodes.new("ShaderNodeValue")
valueB.location = (principled.location[0] - 200, principled.location[1]-300)
valueB.outputs[0].default_value = 0.5
mat.node_tree.links.new(valueB.outputs[0], principled.inputs['Roughness'])

Rename the material

mat.name = 'A_' + mat.name

Rename the the image

image_node = next((n for n in nodes if isinstance(n, bpy.types.ShaderNodeTexImage)), None)
if image_node is not None:
    image_node.image.name = 'A_' + image_node.image.name
