error getting n_spikes from get_cluster_spike_waveforms

[jennifertsai]

Hi! I am trying to write some code to filter out low n_spikes in my phy input data. I have tried this following code:
waveforms = model.get_cluster_spike_waveforms(cluster_id)
n_spikes, n_samples, n_channels_loc = waveforms.shape

This works for most cluster_ids, but there are a few cluster_ids where I keep getting this assertion error:

Any advice on how to fix this?
