• Subsystem: ipld & bitswap

Type: bug

Severity: critical

Description: Error: multihash unknown function code: 0x0

Steps to reproduce the error:

Just was running a js-ipfs node when it out of a sudden crashed. Sadly didn't have debug enabled so no debug logs for that.

Fix: More try/catch in bitswap as this is yet another critical crash
