Failed to make RPC request — pegnetd get rates

[ilzheev]

I have written a script that calculates average FCT price using PegNet.

pegnetd is fully synced:

pegnetd[5412]: time="2020-09-04T02:22:28Z" level=info msg="status report" height=261018
pegnetd[5412]: time="2020-09-04T03:22:05Z" level=info msg="status report" height=261024
pegnetd[5412]: time="2020-09-04T04:22:15Z" level=info msg="status report" height=261030
pegnetd[5412]: time="2020-09-04T05:22:06Z" level=info msg="status report" height=261036
pegnetd[5412]: time="2020-09-04T06:22:02Z" level=info msg="status report" height=261042
pegnetd[5412]: time="2020-09-04T07:22:04Z" level=info msg="status report" height=261048

My script makes 500 sequential requests pegnetd get rates {height}.
pegnetd returns this error for exactly the same heights:

pegnetd get rates 260814
Failed to make RPC request
Details:
jsonrpc2.Error{Code:ErrorCode{-32809}, Message:"Not Found", Data:"could not find what you were looking for"}

It's not a pokemon bug, because each run I get exactly the same "failed" heights:
