My app is supposed to parse JSON data and display it in a recycler view. When I run the app, it crashes with the following error: 
I've re-checked my code multiple times to make sure I am calling the correct resource files, but I still cant find the source of the issue. The logcat tells me the issue is in the onBindViewHolder method in the recycler view adapter class, but everything looks normal to me. Can anyone point me in the right direction? Here is the relevant code:
Recycler View Adapter:
public class IndRvAdapter extends RecyclerView.Adapter<IndRvAdapter.MyViewHolder> {
private Context context;
private List<Ind> indList;
public IndRvAdapter(Context context, List<Ind> indList) {
this.context = context;
this.indList = indList;
}
@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view;
LayoutInflater inflater = LayoutInflater.from(context);
view = inflater.inflate(R.layout.ind_card, viewGroup, false);
final MyViewHolder viewHolder = new MyViewHolder(view);
viewHolder.indView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(context, SingleInd.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("pacshort", indList.get(viewHolder.getAdapterPosition()).getPacshort());
i.putExtra("supopp", indList.get(viewHolder.getAdapterPosition()).getSuppopp());
i.putExtra("candname", indList.get(viewHolder.getAdapterPosition()).getCandname());
i.putExtra("district", indList.get(viewHolder.getAdapterPosition()).getDistrict());
i.putExtra("amount", indList.get(viewHolder.getAdapterPosition()).getAmount());
i.putExtra("party", indList.get(viewHolder.getAdapterPosition()).getExpParty());
i.putExtra("payee", indList.get(viewHolder.getAdapterPosition()).getPayee());
i.putExtra("date", indList.get(viewHolder.getAdapterPosition()).getDate());
i.putExtra("origin", indList.get(viewHolder.getAdapterPosition()).getOrigin());
i.putExtra("source", indList.get(viewHolder.getAdapterPosition()).getSource());
context.startActivity(i);
}
});
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, int i) {
myViewHolder.pacshorts.setText(indList.get(i).getPacshort());
myViewHolder.supOpp.setText(indList.get(i).getSuppopp());
myViewHolder.candName.setText(indList.get(i).getCandname());
myViewHolder.district.setText(indList.get(i).getDistrict());
}
@Override
public int getItemCount() {
return indList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder{
TextView pacshorts, supOpp, candName, district;
LinearLayout indView;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
pacshorts = itemView.findViewById(R.id.tv_pacshort);
supOpp = itemView.findViewById(R.id.tv_suppopp);
candName = itemView.findViewById(R.id.tv_candname);
district = itemView.findViewById(R.id.tv_district);
indView = itemView.findViewById(R.id.ind_view);
}
}
}
