Token object has no attribute data

Wrongfully reported as LaunchPlatform/beancount-parser#6.

I get the following traceback on my ledger:

I have not yet tried to minimise the ledger to find the problem.

Can you please provide a sample beancount file for reproducing this error? Also, I just fixed many of the bugs and upgraded the beancount parser to latest one. There are many bugs has been fixed in between. Can you please try again and see if the problem is now gone?
