When making the below request I get the above error
curl --location --request POST 'https://deep-index.moralis.io/api/v2/0x5a666c7d92e5fa7edcb6390e4efd6d0cdd69cf37/events?chain=eth&topic=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef&limit=500' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'X-API-Key:<API_KEY>' \
--data-raw '{}'
What is the case in which this error occurs?
