> Attempting to use blob conversion functions e.g. textAsBlob, from 3.0 - 3.7 results in:
> {noformat}
> Exception in thread "main" org.apache.cassandra.exceptions.InvalidRequestException: Unknown function textasblob called

> The following snippet will reproduce the issue
> {code}
> String table = String.format("%s.%s", "test_ks", "test_table");
> String schema = String.format("CREATE TABLE %s (test_text text, test_blob blob, PRIMARY KEY(test_text));", table);
> String insertStatement = String.format("INSERT INTO %s (test_text, test_blob) VALUES (?, textAsBlob(?))", table);
> File tempDir = Files.createTempDirectory("tempDir").toFile();
> CQLSSTableWriter sstableWriter = CQLSSTableWriter.builder()
>         .forTable(schema)
>         .using(insertStatement)
>         .inDirectory(tempDir)
>         .build();
> {code}
> This is caused in FunctionResolver.get(...) when candidates.addAll(Schema.instance.getFunctions(name.asNativeFunction())); is called, as there is no system keyspace initialised.
