Hi,
You seem to be using a special structure, probably never encountered or thought of.
Channel Array block or compositions applications can be complicated.
But just the traceback is not enough for me to troublehsoot. If you can send the file would be perfect or a snapshot of this composition from MDFValidator to understand this structure (Famos is not so helping) You could also scramble/anonymize the file using asammdf if you have confidentiality issues.

data = np.array(data, dtype=np.float32)
use this on ur dataset
