uniform1fv failed #260
Description
gl.shaderSource(
xxxShader,
`
....
uniform float h[6];
....
`
);
....
gl.uniform1fv(
gl.getUniformLocation(xxxProgram, 'h'),
new Float32Array([
1.0,2.0,3.0,4.0,5.0,6.0
])
);
When I am using headless-gl,
I'm trying to pass an array with variable 'h' into the fragment shader, but the rendering result is not working.
But if I write the variable 'h' in the fragment shader, there is no problem.
The code is effective in the browser.

It looks like the
infovariable returned null, causing the value obtained by thegl.getUniformLocationmethod to be also null.Try this way:
gl.getUniformLocation(xxxProgram, 'h[0]'), it also works well on WEBGL.Accept array uniform names without [0] in getUniformLocation
