A GitHub issue was created and a PR with a fix was merged by the PO.
Expected behavior
blockchain.stream(start, stop, only_ops=True) should return all operations, including virtual ops, contained in the block range from start to stop. The same should be possible via Block(blocknum, only_ops=True) for individual blocks. If a block does not contain operations, the calls should return an empty list. While this situation is rare for current blocks, it is present frequently on early Steem blocks, testnets and Steem forks.
Actual behavior
blockchain.stream(start, stop, only_ops=True) and Block(blocknum, only_ops=True) fail with a BlockDoesNotExistsException if the block contains no operations.
How to reproduce
from beem.blockchain import Blockchain
b = Blockchain()
for op in b.stream(start=1000, stop=1001, only_ops=True):
print(op)
or
from beem.block import Block
b = Block(1000, only_ops=True)
Output:
Traceback (most recent call last):
