[json.exception.type_error.302] "type must be number, but is ", j.type_name()

[lemi03]

im am currently working on loading models in openGL by reading and parsing the .gltf files. But whenever I run the program, I get redirected to the this line with an error:
JSON_THROW(type_error::create(302, concat("type must be number, but is ", j.type_name()), &j))
At first I thought it was the accessor["type"], since I thought it was converted into an integer, but when I stepped through the program I noticed that the error ocurred right before this line:
unsigned int componentType = accessor["componentType"];
Now I am not sure where the issue is located.
Here is my code for getting the floats and indices:

`std::vector Model::getFloats(json accessor)
{
std::vector floatVec;

// Get properties from the accessor
unsigned int buffViewInd = accessor.value("bufferView", 1);
unsigned int count = accessor["count"];
unsigned int accByteOffset = accessor.value("byteOffset", 0);
std::string type = accessor["type"];

// Get properties from the bufferView
json bufferView = JSON["bufferViews"][buffViewInd];
unsigned int byteOffset = bufferView["byteOffset"];

// Interpret the type and store it into numPerVert
unsigned int numPerVert;
if (type == "SCALAR") numPerVert = 1;
else if (type == "VEC2") numPerVert = 2;
else if (type == "VEC3") numPerVert = 3;
else if (type == "VEC4") numPerVert = 4;
else throw std::invalid_argument("Type is invalid (not SCALAR, VEC2, VEC3, or VEC4)");

// Go over all the bytes in the data at the correct place using the properties from above
unsigned int beginningOfData = byteOffset + accByteOffset;
unsigned int lengthOfData = count * 4 * numPerVert;
for (unsigned int i = beginningOfData; i < beginningOfData + lengthOfData; i += 4)
{
	unsigned char bytes[] = { data[i], data[i + 1], data[i + 2], data[i + 3] };
	float value;
	std::memcpy(&value, bytes, sizeof(float));
	floatVec.push_back(value);
}

return floatVec;

}`

`std::vector Model::getIndices(json accessor)
{
std::vector indices;

// Get properties from the accessor
unsigned int buffViewInd = accessor.value("bufferView", 0);
unsigned int count = accessor["count"];
unsigned int accByteOffset = accessor.value("byteOffset", 0);
unsigned int componentType = accessor["componentType"];

// Get properties from the bufferView
json bufferView = JSON["bufferViews"][buffViewInd];
unsigned int byteOffset = bufferView["byteOffset"]; //exception

// Get indices with regards to their type: unsigned int, unsigned short, or short
unsigned int beginningOfData = byteOffset + accByteOffset;
if (componentType == 5125)
{
	for (unsigned int i = beginningOfData; i < byteOffset + accByteOffset + count * 4; i += 4)
	{
		unsigned char bytes[] = { data[i], data[i + 1], data[i + 2], data[i + 3] };
		unsigned int value;
		std::memcpy(&value, bytes, sizeof(unsigned int));
		indices.push_back((GLuint)value);
	}
}
else if (componentType == 5123)
{
	for (unsigned int i = beginningOfData; i < byteOffset + accByteOffset + count * 2; i += 2)
	{
		unsigned char bytes[] = { data[i], data[i + 1] };
		unsigned short value;
		std::memcpy(&value, bytes, sizeof(unsigned short));
		indices.push_back((GLuint)value);
	}
}
else if (componentType == 5122)
{
	for (unsigned int i = beginningOfData; i < byteOffset + accByteOffset + count * 2; i += 2)
	{
		unsigned char bytes[] = { data[i], data[i + 1] };
		short value;
		std::memcpy(&value, bytes, sizeof(short));
		indices.push_back((GLuint)value);
	}
}

return indices;

}`

FYI, you need three backticks around a code block, single ones only work on a single line.
