[Mne_analysis] TypeError: string indices must be integers

Dear experts:
I am running this code. 


  # Get labels for FreeSurfer 'aparc' cortical parcellation with 34 labels/hemi
    labels_parc = mne.read_labels_from_annot(
        subject, parc='aparc', subjects_dir=subjects_dir)
    
    label_ts = mne.extract_label_time_course(
        [stc],labels_parc, src, mode='mean', allow_empty=True)

And I get this error message. I know there is some issues with the numbers but I am using the code from the tutorial so I don’t know why it doesn’t work probably because is my own data. 


Traceback (most recent call last):
