Comparison google trends: ConversionError: Failed to convert value(s) to axis units:

[Manolo1182]

I have been trying to reproduce the comparison with the google trends file, buy I keep getting this error and I have not been able to figure out why, is it a problem with the data type of the tesla_chnagepoints data values?
Thanks in advance, great tutorial!!!
