This is only happening in only one table. The contributions table. Here’s is my code
.....
protected List<Contributions> doInBackground(Integer... params) {
try {
BackendlessDataQuery query = new BackendlessDataQuery();
BackendlessCollection<Contributions> data = Contributions.find( query );
addItemsContributionList( data );
}catch (Exception e){
e.printStackTrace();
}
....
And here is the erroe stack
BackendlessException{ code: 'Internal client exception', message: 'Unexpected response code for CONNECT: 400' }
