Using GL_TEXTURE_2D_ARRAY as a draw target

I've created an array of 2D textures and initialized it with glTexImage3D. Then I attached separate textures to color attachments with glFramebufferTextureLayer, Framebuffer creation doesn't throw an error and everything seems fine until the draw call happens.

When shader tries to access color attachment the following message appears:

OpenGL Debug Output message : Source : API; Type : ERROR; Severity : HIGH;
GL_INVALID_OPERATION error generated. <location> is invalid.

Shaders are accessing layers of an array with location qualifier:

layout (location = 0) out vec3 WorldPosOut; 
layout (location = 1) out vec3 DiffuseOut; 
layout (location = 2) out vec3 NormalOut; 
layout (location = 3) out vec3 TexCoordOut; 

Documentation says that glFramebufferTextureLayer works just like glFramebufferTexture2D, except the layer parameter, so can I use location qualifiers with texture array, or some other way exsists?
