Sub0 Workshop: Price feed results remain empty in chainstate despite deployment with valid pairings

[oracle58]

After following all steps including deploy_price_feed call and verification that get_deployment includes my testpair:

{
      "name": "testpair",
      "owner": "42kS2Uj8SvTAtZYJJ3mbHK33Mk2w9a8aPkcKpirZKguvTzA3",
      "contractId": "0x19771db36c8c3ee91af607cf45c6674325dd081220a7bb4dea58d0ac6d97e265",
      "createdAt": "1,669,680,375,000",
      "expiredAt": "1,669,683,975,000"
    }

I am not able to retrieve the data feed in the chainstate.

I tried various valid pairings and verified availability using https://api.coingecko.com/api/v3/simple/price?ids={token0}&vs_currencies={token1}, which e.g. returns:

{"polkadot":{"usd":5.12}}

for token0 = polkadot, token1 = usd.

In the polkadot.js app (dev->chainstate section), I only get empty responses, when I select Storage -> phatOracle -> my account as param -> press +:

phatOracle.priceFeeds: Option<PhatOffchainRollupOraclePalletPriceQuote>
[ ]

In a nutshell

• Wallet is successfully linked
• I used the correct meta data and contract id in the attachment procedure
• The contract and polkadot.js app point to Phala poc5 testnet endpoint
• I verified the used pairings exist on the mentioned gecko endpoints and use the full name for token0 and abbreviation (symbol) for token1 (and I followed the example provided in the readme, anyway)

Yet the priceFeeds remain empty in the chainstate.

Thanks for any help!

Scheduler went down. To enable this action manually, you will need to do the following:

1. "Attach" the sub_price_feed.contract and load you contract id into the parameter
2. Interact with the contract by selecting maybe_init_rollup. You'll get a result similar to the first results in the screenshot

   sub_price_feed.maybe_init_rollup
   0x8235a60f02d9fb4beb951f6a783f2ea68f606a5f0882b24de2f49cae189f1df1
   11/29/2022, 5:09:55 PM
   {
   "Ok": "0x3cf2aedb55c95a30f7b7d971e642911c9b564519845e4237114ec512791c35e9"
   }

3. Next, interact with the contract and select feed_price. This will feed the price to the Phala PoC5 Testnet pallet and return a similar result:

   sub_price_feed.feed_price
   0x8235a60f02d9fb4beb951f6a783f2ea68f606a5f0882b24de2f49cae189f1df1
   11/29/2022, 5:10:29 PM
   {
   "Ok": "0x700442c9ef6163659e4fa4e2acb6ff97071f9e025f60f1f7ae20b8ab05de379b"
   }

5. Now you can go to polkadot.js.org and verify the price feed here.

Thanks a lot for the support! Now I am getting response(s) as expected, e.g.:

phatOracle.priceFeeds: Option<PhatOffchainRollupOraclePalletPriceQuote>

No more issues from my side, if you like, fell free to close -- and thanks again :)!

Edit: After this step is complete the NFT is automatically sent to the owner of the respective sub_feed_price contract, right?
