I am running ari-proxy 5.2.3 but getting following error

Error: failed to connect to ARI: failed to create websocket configuration: Failed to construct websocket config: parse "\"ws://localhost:8088/ari/events\"?app=my_test_app": invalid URI for request
t=2022-06-02T13:04:47+0000 lvl=info msg="starting ari-proxy server" version=5.2.3

I think you have quotes when it is unnecessary (maybe you are using them in a script).
Try to check ARI_WEBSOCKET_URL variable.
