Cascaded shadow maps Error on texture generation

OpenGL OpenGL: Advanced Coding

I am developing cascaded shadow maps with a single draw call using geometry shader for the different textures. I am creating a texture using the following code :

    GLuint texture;
	glGenTextures(1, &texture);
	glBindTexture(GL_TEXTURE_2D_ARRAY, texture);
	glTextureStorage3D(GL_TEXTURE_2D_ARRAY, 1, GL_DEPTH_COMPONENT32F, width, height, mNumCascades);
	glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
	glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
	glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
	glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);

I get an error of GL_INVALID_OPERATION and I can’t figure out what is wrong. I read that it has to do with the levels, here 1, but I can’t figure out what value I have to pass in. By the way do you know how to format my code in the question here? Thanks in advance

I used this and it worked fine :

glTexImage3D(GL_TEXTURE_2D_ARRAY, 0, GL_DEPTH_COMPONENT32F, width, height, mNumCascades, 0, GL_DEPTH_COMPONENT, GL_FLOAT, 0);

glTextureStorage3D() is a DSA function which takes the texture handle as the first argument.

I think you meant to call glTexStorage3D() which operates on the bound texture of the specified type.
