If the error is not handled, the running daemon will continuously
print the following error message:
```
Traceback (most recent call last):
File "lbry/extras/daemon/exchange_rate_manager.py", line 77, in get_rate
File "lbry/extras/daemon/exchange_rate_manager.py", line 189, in get_rate_from_response
KeyError: 0
```
This started happening when the UPBit exchange decided to delist
the LBC coin.
Normally `json_response` should be a dictionary, not a list,
so `json_response[0]` causes an error.
By checking for the `'error'` key, we can raise the proper exception.
Once this is done, the message will be a warning, not a traceback.
```
WARNING lbry.extras.daemon.exchange_rate_manager:92:
Failed to get exchange rate from UPbit: result not found

Currently `lbrynet blob get <hash>` does not work to download
single blobs which are not already present in the system.
The function locks up and never returns.
It only works for blobs that are in the `blobfiles` directory
already.
This bug is reported in lbryio/lbry-sdk, issue #2070.
Maybe this script can be investigated, and certain parts
can be added to `lbry.extras.daemon.daemon.jsonrpc_blob_get`
in order to solve the previous issue, and finally download
single blobs from the network (peers or reflector servers).
