Seems that squashing my app migrations is returning the following error
when running `migrate`. As far as I can see,
0060_auto_20190828_0652.update_store_locator_in_cart_page is an invalid
identifier because it starts with a number. Perhaps checking running
`getattr` before to avoid this issue.

I am not sure whether this is a Django issue or some other library
conflict.

Comment:

I think you missed a comment at the begging of a squashed migration (see
#22983):
{{{
# Functions from the following migrations need manual copying.
# Move them and any dependencies into this file, then update the
# RunPython operations to refer to the local versions:
# store.migrations.0060_auto_20190828_0652
