Python- not in index error (one-hot encoded)

Question

I'm working on the Titanic dataset and one-hot applied to all columns. So everything 0 and 1.

However, I get the following error in train operation. I tried many things but I could not find the solution. I tried to explain the error as much as I can, I hope you can understand the problem easily. Thank you for your time.

Traceback (most recent call last):

The part of the code where the error came from run_train.py:

data_pars['train'] = {'Xtrain' : dfX[colsX].iloc[:itrain, :],
                          'ytrain' : dfX[coly].iloc[:itrain],
                          'Xtest'  : dfX[colsX].iloc[itrain:ival, :],
                          'ytest'  : dfX[coly].iloc[itrain:ival],

                          'Xval'   : dfX[colsX].iloc[ival:, :],
                          'yval'   : dfX[coly].iloc[ival:]
                          }
