Custom sounds

I'm trying to change the crash sounds of my shopping cart mod, similar to how the piano has a custom sound when a beam breaks. I made a .sbeam file and I also have the sound effect in a sounds folder, but when I spawn the vehicle a bunch of errors appear in the console.

I haven't made sounds before, can someone tell me what I'm doing wrong?

Code:

{
    "sounds":[
        ["group", "filename",  "profile",            "nodeName", "source",                      "factor", "offset", "minVolume", "minPitch", "maxVolume", "maxPitch", "pitchBlendInStartValue", "pitchBlendInEndValue", "volumeBlendInStartValue",  "volumeBlendInEndValue", "volumeBlendOutStartValue", "volumeBlendOutEndValue", "volumeModifiers",   "pitchModifiers"],
        ["default", "shopping_cart_hit", "AudioDefaultLoop3D", "a3",   "",            1,        0,        100,           2,          100,           2,        1,                       1,                      1 ,                       1,                       1000,                       1000,                     [], []              ],
    ],
}
