INVALID_FUNCTION_ARGUMENT

Error message

e.getMessage()

What it means

Catch-and-rethrow in HyperLogLogUtils.mergeState: merging two HyperLogLogs whose bucket counts differ throws inside the library; because the counts are not accessible, the original exception is rethrown with its raw message (hence the generic 'e.getMessage()' text) as INVALID_FUNCTION_ARGUMENT.

Solutions

1. Ensure all HLL inputs to the merge/union were created with the same number of buckets
2. Create HLLs from the same engine/version with identical index configurations
3. Rebuild the HLLs from raw data with matching bucket counts before merging
