Getting a Validation error when using vkcmdDraw() due to not having shader objects bound even though they are bound

Vulkan

I have 2 valid shader objects vert, and frag, but whenever I try to use vkCmdDraw I get hit with this

VUID-vkCmdDraw-None-08607(ERROR / SPEC): msgNum: 481152932 - Validation Error: [ VUID-vkCmdDraw-None-08607 ] Object 0: handle = 0x297485654f0, type = VK_OBJECT_TYPE_COMMAND_BUFFER; | MessageID = 0x1cadcfa4 | vkCmdDraw():  A valid VK_PIPELINE_BIND_POINT_GRAPHICS pipeline must be bound with vkCmdBindPipeline or shader objects with vkCmdBindShadersEXT before calling this command. The Vulkan spec states: If the shaderObject is enabled, either a valid pipeline must be bound to the pipeline bind point used by this command, or a valid combination of valid and VK_NULL_HANDLE shader objects must be bound to every supported shader stage corresponding to the pipeline bind point used by this command (https://vulkan.lunarg.com/doc/view/1.3.290.0/windows/1.3-extensions/vkspec.html#VUID-vkCmdDraw-None-08607)

My code is as such

void bindPipeline(Pipeline pline, VkCommandBuffer cBuf)
{
    VkBool32 cbEnable = pline.colorBlending;
    vkCmdSetColorWriteMaskEXT_(cBuf, 0, 1, &pline.colorWriteMask);

    vkCmdSetColorBlendEnableEXT_(cBuf, 0, 1, &cbEnable);
    vkCmdSetLogicOpEnableEXT_(cBuf, pline.logicOpEnable);

    vkCmdSetDepthTestEnable(cBuf, pline.depthTestEnable);
    vkCmdSetDepthBiasEnable(cBuf, pline.depthBiasEnable);
    vkCmdSetDepthClampEnableEXT_(cBuf, pline.depthClampEnable);
    vkCmdSetDepthClipEnableEXT_(cBuf, pline.depthClipEnable);
    vkCmdSetStencilTestEnable(cBuf, pline.stencilTestEnable);
    vkCmdSetDepthWriteEnable(cBuf, pline.depthWriteEnable);
    vkCmdSetDepthBoundsTestEnable(cBuf, pline.depthBoundsEnable);
    vkCmdSetAlphaToCoverageEnableEXT_(cBuf, pline.alphaToCoverageEnable);
    vkCmdSetAlphaToOneEnableEXT_(cBuf, pline.alphaToOneEnable);

    vkCmdSetColorWriteMaskEXT_(cBuf, 0, 1, &pline.colorWriteMask);
    vkCmdSetPolygonModeEXT_(cBuf, pline.polyMode);
    vkCmdSetPrimitiveTopology(cBuf, pline.topology);
    vkCmdSetRasterizerDiscardEnable(cBuf, pline.reasterizerDiscardEnable);
    vkCmdSetPrimitiveRestartEnable(cBuf, pline.primitiveRestartEnable);
    vkCmdSetRasterizationSamplesEXT_(cBuf, pline.rastSampleCount);
    vkCmdSetFrontFace(cBuf, pline.frontFace);
    vkCmdSetCullMode(cBuf, pline.cullMode);

    if (pline.colorBlending == VK_TRUE)
        vkCmdSetColorBlendEquationEXT_(cBuf, 0, 1, &pline.colorBlendEq);

    if (pline.logicOpEnable == VK_TRUE)
        vkCmdSetLogicOpEXT_(cBuf, pline.logicOp);
    if (pline.depthTestEnable == VK_TRUE)
    {
        vkCmdSetDepthBounds(cBuf, pline.minDepth, pline.maxDepth);
        vkCmdSetDepthCompareOp(cBuf, pline.depthCompareOp);
    }
    vkCmdSetSampleMaskEXT_(cBuf, 1, pline.sampleMask);
    vkCmdBindShadersEXT_(cBuf, 1, (VkShaderStageFlagBits[1]){VK_SHADER_STAGE_VERTEX_BIT}, &pline.vert.shader);
    vkCmdBindShadersEXT_(cBuf, 1, (VkShaderStageFlagBits[1]){VK_SHADER_STAGE_FRAGMENT_BIT}, &pline.frag.shader);
    int vertexDescCount = pline.vert.VertexDescriptons;
    vkCmdSetVertexInputEXT_(cBuf, vertexDescCount, pline.vert.bindingDesc, vertexDescCount, pline.vert.attrDesc);
}

void unBindPipeline(VkCommandBuffer cBuf)
{
    vkCmdBindShadersEXT_(cBuf, 1, (VkShaderStageFlagBits[1]){VK_SHADER_STAGE_VERTEX_BIT}, VK_NULL_HANDLE);
    vkCmdBindShadersEXT_(cBuf, 1, (VkShaderStageFlagBits[1]){VK_SHADER_STAGE_FRAGMENT_BIT}, VK_NULL_HANDLE);
}

which should satisfy the conditions required for this right?

my execution callback for the given renderpass is as so

void helloTriangleCallback(RenderPass pass, VkCommandBuffer cBuf)
{
    bindPipeline(pass.pl, cBuf);

    vkCmdDraw(cBuf, 3, 1, 0, 0);

    unBindPipeline(cBuf);
}

Why would this create such a result?

turns out my shader objects were not set, for whatever reason
