I did upgrade to the following
"@moralisweb3/common-evm-utils": "^2.12.0",
"moralis": "^2.12.0",
then, l changed disable_total to the disableTotal, because:
Moralis SDK Error: [C0005] Request contains unknown parameter: disable_total. This operation supports the following parameters: address, chain, format, limit, totalRanges, range, cursor, normalizeMetadata, disableTotal
and still, I get NULL for the total. What else can be done to make it work?
