Cannot parse varint value from

Error message

Cannot parse varint value from "%s"

What it means

InvalidTypeException from VarintCodec.parse: new BigInteger(value) threw NumberFormatException — the string is not a valid arbitrary-precision integer literal (non-numeric characters, malformed sign, or empty after handling of null/empty/'NULL').

Solutions

1. Supply a plain optionally-signed decimal integer literal (digits only, no exponent or separators)
2. Strip whitespace, quotes, or locale formatting from the value
3. Use a value within the intended range and re-check the string encoding of the source data

When it happens

Trigger: Thrown at src/java/org/apache/cassandra/cql3/functions/types/TypeCodec.java:2067 when the library encounters an invalid state.
