COMMIT results in "Invalid or unsupported FunctionCode"

When I execute a "commit" statement, this results in the following error:

Error: Invalid or unsupported FunctionCode
    at Result.handle (.../node_modules/hdb/lib/protocol/Result.js:113:13)
    at handleReply (.../node_modules/hdb/lib/protocol/Statement.js:173:12)
    at receive (.../node_modules/hdb/lib/util/Queue.js:114:18)
    at Connection.receive (.../node_modules/hdb/lib/protocol/Connection.js:455:5)
    at TLSSocket.ondata (.../node_modules/hdb/lib/protocol/Connection.js:289:12)
    at TLSSocket.emit (node:events:519:28)

The commit works, and I can circumvent the problem by try-catching the exception and ignoring it, but it would be nice if this was supported.

Start in lib/protocol/Result.js at handle(), then trace the reply flow through Statement.js, Queue.js, and Connection.js. Reproduce the issue with a COMMIT statement and inspect how its FunctionCode is handled. Done means COMMIT completes without raising the unsupported-FunctionCode error, with coverage for this result if the repository has a relevant test location.
