'unexpected indent' error during sync when loading .csv file

I tried the suggestions in the stackoverflow thread, no luck.

i’m not sure what is going on but I noticed that I can upload the file in one experiment, but not another.
described more in detail here:

in the derp2 experiment, if I import prac_toy_graphDataframe.csv I do not receive the unexpected indent error when syncing and I am able to extract the information.
