Please make sure you’re following the [Lua UDF - Best Practices](https://www.aerospike.com/docs/udf/best_practices.html), and quote the lines from the UDF log that show what is going on. When you have an error with code 100, further details are most likely to present themselves in the log.

Next, please quote your UDF code here. Hard to debug code you can’t see. For comparison, look at this similar issue: [Unable to get simple filter/map to work using Python client (AER-4251) [Released]](https://discuss.aerospike.com/t/unable-to-get-simple-filter-map-to-work-using-python-client/1647)
