[jorg1piano]

When trying to fetch wallets on solana mainnet the response always returns 0 tokens:

package main

import (
	"coin_market_tracker/env"
	"fmt"

	"github.com/covalenthq/covalent-api-sdk-go/chains"
	"github.com/covalenthq/covalent-api-sdk-go/covalentclient"
	"github.com/covalenthq/covalent-api-sdk-go/quotes"
	"github.com/covalenthq/covalent-api-sdk-go/services"
)

func main() {
	env.LoadKeysFromEnv()
	var Client = covalentclient.CovalentClient(env.GetApiKeys().CovalentHqApiKey)

	solAddress := "ENcEhwjQbXKxsPyEJWSVnn8S2mZfczMeKpLJhBDBHsHg"
	currency := quotes.USD
	NoSpam := false
	resp, _ := Client.BalanceService.GetTokenBalancesForWalletAddress(chains.SolanaMainnet, solAddress, services.GetTokenBalancesForWalletAddressQueryParamOpts{
		QuoteCurrency: &currency,
		NoSpam:        &NoSpam,
	})
	fmt.Println(len(resp.Data.Items), "tokens found") // prints: 0 tokens found
}
