ERPparamGroup().get_ERPparam() throwing error

[dillancellier]

ERPparamGroup().get_ERPparam().plot() errors when there was no model fit for that ERP, returns plot of raw data and peak-less model fit, but errors in ERPparam/plts/model.py:
in plot_ERPparam(model,ax, y_label)
line 42 ax.scatter(model.time[model.peak_indices_[:,1]], model.signal[model.peak_indices_[:,1]], color='r', label='Peak fit')
yields IndexError: too many indices for array

ERPparamGroup().get_ERPparam() also erroring on random other trials-- don't understand why (example trial attached)

fit_params = {'max_n_peaks':4, 'peak_width_limits':(0.01,np.inf), 'peak_threshold':1.5, 'min_peak_height':20, 'skewed_gaussian':False}
es = ERPparamGroup(**fit_params)
es._gauss_overlap_thresh = 0.75
es.fit(signals=erroring,time=time, time_range=[0,1], baseline=[-0.5,0])
