Scrape fails after 46,147 blocks - receipt_data is NoneType

[whydna]

Describe the bug
Setup went smoothly using a local Geth node. Ran ether_sql scrape_block_range and everything seemed to be working smoothly. It now seems to be stuck on block 46,147 with the following error every time I try to run it:

    receipt = cls(transaction_hash=to_hex(receipt_data['transactionHash']),
TypeError: 'NoneType' object is not subscriptable

If I skip that block by running: scrape_block_range --start_block_number 46148

It will scrape a few more blocks and then fail on the next one without receipt data:
