Parse viabtc miner by looking for the first '/' after the '/ViaBtc/' , instead of the last '/' from end of the string. Sometimes you get a random '/' there which makes you include garbage.

I tested on blockhash 000000000000000009d3199a377cb4320d5c7c5256aff82f1f8f29b3662af198 after seeing it come in garbled but decided it wasn't worth including this in the large set of unit test blocks.
npm test
npm run msgs and viabtc miners are good
