Get /erc20/{address}/price error on ropsten network (factoryname resolve))

Technical Issue Reporting
#1

I try to get a tokens price info on the ropsten testnet. For ETH it all works but no matter which factory name I try on ropsten I get a 400 Undocumented Error: Bad Request

Response body

{
  "message": "No valid exchange found for the provided chain and/or to_block"
}

Does anyone have an idea why?

#2

If anyone else is running into this problem. The endpoint is not defined for ropsten, since price data on testNet is just gibberish.

#3

yes, I don’t expect to have price data on ropsten because there is not exchange that we process for price data
