Texture File Appears Blank on GLSL Shader in Scene!

I have some shaders applied to planes in a scene, in that shader there is supposed to be a texture file loaded to the frag color through a Texture2D function. For some reason my planes appear blank in the scene, despite being visible if I only use a vec4 color as the output. Ive checked with the Three JS Journey discord and they can find anything wrong with the my code. Im honestly unsure what the problem is at this point, can someone help me pin down and fix the issue?
Here is what it looks like with the texture as the frag color (blank),

and here is the UV coordinates as the frag color
