imageLoad() not giving the expected result when using r32f format

[Graph3r]

I made a compute shader that would use the depth buffer texture as a input for post processing, the imageLoad() returns a vec4, but the image only has one channel. I first tried to just write imageLoad(depthImage, gid).r but nothing happened, I tried going through r, g, b and a channels too, but it wouldn't work either. When using a vertex and fragment shader to render the depth texture as a quad, it worked and displayed the depth as a grayscale. Why doesn't the imageLoad do anything, here is parts of the code if it helps:

// Setup
depthTexture = glGenTextures();
glBindTexture(GL_TEXTURE_2D, depthTexture);
glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT32F, width, height, 0, GL_DEPTH_COMPONENT, GL_FLOAT, (FloatBuffer) null);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glFramebufferTexture2D(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_TEXTURE_2D, depthTexture, 0);
computeProgram = ShaderProgram.fromFiles("src\\game\\test.compute", "offscreenrenderer", 0);
quad = new FullscreenQuad();
computeProgram.use();
glBindImageTexture(0, renderedTexture, 0, false, 0, GL_READ_ONLY, GL_RGBA32F);
glBindImageTexture(1, depthTexture, 0, false, 0, GL_READ_ONLY, GL_R32F);
glBindImageTexture(2, processedTexture, 0, false, 0, GL_WRITE_ONLY, GL_RGBA32F);
computeProgram.unuse();

// Methods in the code for starting the rendering and for doing the post processing:
public void start() {
    glBindFramebuffer(GL_FRAMEBUFFER, frameBuffer);
    //glBindRenderbuffer(GL_RENDERBUFFER, depthBuffer);
    glViewport(0, 0, width, height);
}

public void runPostProcess() {
    computeProgram.use();
    glDispatchCompute((int) Math.ceil(width / 16.0), (int) Math.ceil(height / 16.0), 1);
    glMemoryBarrier(GL_SHADER_IMAGE_ACCESS_BARRIER_BIT);
    computeProgram.unuse();

    glBindFramebuffer(GL_FRAMEBUFFER, 0);
    glClear(GL_COLOR_BUFFER_BIT);
    quad.setTexture(processedTexture);
    quad.render();
}

Simple debugging in the compute shader:

#version 430
layout(local_size_x = 16, local_size_y = 16) in;

layout(binding = 0, rgba32f) uniform image2D inputImage; // Works
layout(binding = 1, r32f) uniform image2D depthImage; // Doesn't work
layout(binding = 2, rgba32f) uniform image2D outputImage; // Works

void main() {
    ivec2 pos = ivec2(gl_GlobalInvocationID.xy);
    imageStore(outputImage, pos, imageLoad(depthImage, pos));
}
