if (!result.data || !result.data.type) {
        throw new Error(
          "Price Table not found, contract may not be initialized"
        );
      }

its cause the pyth price object was not found.
i need to get the dynamicObjectField of the pyth State Id, and it doesnt return me the proper one

cause its not able to get the price table info for the pythStateId

I even tested this code, separately outside the package, and the result.data will have value only when I used archive node.

so i testeed with sui public node, which is archived node, and my normal full node. data was returned only using sui archived node.

Is it not possible to use the price feed with a full node? Do we need an archive node for that?
