A bug happened!

Gaia Version

v19.1.0

How to reproduce?

Hi,
I am using to get particular event transactions but it is giving me following response:

{
"code": 13,
"message": "query cannot be empty",
"details": []
}

API: http:///cosmos/tx/v1beta1/txs?events=message.sender='cosmos1w5jleaknx4qhh8exw86eea0ckpeqzuu68kca3l'&page=1&limit=10

It was working with earlier versions

Use /txs?query= instead of /txs?events=

-<URL>/cosmos/tx/v1beta1/txs?query=message.sender=...
+<URL>/cosmos/tx/v1beta1/txs?events=message.sender=...

Relevant section:

Array of strings
events is the list of transaction event type. Deprecated: post v0.47.x use query instead, which should contain a valid events query.
--

string
query defines the transaction event query that is proxied to Tendermint's TxSearch RPC method. The query must be valid.
