pick() got an unexpected keyword argument 'meg'

Hi,

I am trying to annotate muscle artifacts.

The code is below. PS: the data is generated

import numpy as np
import mne
from   copy       import deepcopy as dpcpy
from mne.preprocessing import annotate_muscle_zscore

np.random.seed(10)

data = np.random.rand(24,1024)
data1 = np.random.rand(24,251)

data_ = np.concatenate((data, data1),axis=1)

ch_names = ["Fp1", "Fp2", "F3", "F4", "C3", "C4", "P3", "P4", "O1", "O2", "F7", "F8", "T7", "T8", "P7", "P8", "Fz", "Cz", "Pz", "M1", "M2", "AFz", "CPz", "POz"]

montage = mne.channels.make_standard_montage('standard_1020')
info = mne.create_info(ch_names=ch_names, sfreq=1000, ch_types='eeg').set_montage(montage, match_case=False)

raw = mne.io.RawArray(data_,info, copy='data', verbose=False)
raw.set_eeg_reference(projection=True)

raw.notch_filter([60, 120])

threshold_muscle = 5

annot_muscle, scores_muscle = annotate_muscle_zscore(
    raw,
    ch_type="eeg",
    threshold=threshold_muscle,
    min_length_good=0.2,
    filter_freq=[110, 140],
)

The TypeError i get is

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

    104 else:
    105     ch_type = {"meg": False, ch_type: True}
--> 106     raw_copy.pick(**ch_type)
    108 raw_copy.filter(
    109     filter_freq[0],
    110     filter_freq[1],
   (...)
    113     n_jobs=n_jobs,
    114 )
    115 raw_copy.apply_hilbert(envelope=True, n_jobs=n_jobs)

TypeError: pick() got an unexpected keyword argument 'meg'

I specified the channel type as eeg.

I don’t know where the error is coming from and why. I am using the example on the documentation
https://mne.tools/stable/auto_examples/preprocessing/muscle_detection.html#annotate-muscle-artifacts

Any help is appreciated. Thanks
