i'm facing the same issue.
i get this error when i run the same query with an account that has many different tokens. the account you mentioned has 50 different tokens!
in my case i just need ada balance. but i don't know how to filter it and just get ada balance. i think it would solve my own problem.

in my case this helped me:
`
query = """
query PaymentAddressSummary ($address: String!){
utxos (
where: {
_and: {
address: { _eq: $address }
}
}
) {
value
}
}

"""

graphql_url = "https://explorer.cardano.org/graphql/"
address = "addr1vqkzkjxm33tms7xr5qjuu92m3ygs8mpfvvyncp3atj08hlgh9n7xs"
data = {"query": query, "variables": {"address": address}}
response = requests.post(
url=graphql_url,
headers={"Content-Type": "application/json"},
data=json.dumps(data),
timeout=60,
)

utxos = response.json().get("data").get("utxos")
balance = sum([utxo['value'] for utxo in utxos])
print(balance)
