Hello @tao.su

I did a quick test with 0#USTSY=RRP and the EMA Java version 3.6.7 L2 - ex450_MP_QueryServiceDiscovery example. It can subscribe to the chain successfully as follows:

RefreshMsg

    domain="MarketPrice Domain"
    solicited
    RefreshComplete
    state="Open / Ok / None / ''"
    itemGroup="00 03"

    name="0#USTSY=RRPS"
    nameType="1"

Hello @tao.su ,

It would be helpful to include the details of how you observe this error with EMA and RTO:

version and language of EMA API
do you observe this error with a simple RTO example ( EMA 450 or 113) or only with the custom app?
was the error received once, or is it reproducible?

I have quick-verified 0#USTSY=RRPS instrument with example consumer EMA JAVA 113, and was able to subscribe as expected.
