ARRAY_AGG: IndexOutOfBoundsException

Hello everyone,

I created the following view

CREATE OR REPLACE VIEW “VIEW”
AS
SELECT
TOKEN,
TYPE,
ARRAY_AGG(TEXT) AS SYMPTOMS_TEXT,
ARRAY_AGG(CODE) AS SYMPTOMS_CODE
FROM “TABLE”
GROUP BY TOKEN, TYPE;

The “TABLE” is an Iceberg file in an “Object Storage” (MinIO (S3)) and we create the view inside a schema in the “Spaces”. I can create the view without errors but when I run a simple SELECT * FROM “VIEW”, I receive the follwing error-message:

SQL-Fehler: SYSTEM ERROR: IndexOutOfBoundsException: index: 32760, length: 36 (expected: range(0, 32768))

The TEXT variable is a VARCHAR field, no entry longer then 24 bytes and the CODE variable is a VARCHAR field aswell, with a fixed length of 36 bytes. An example would look like this

TOKEN TYPE TEXT CODE
A1 MAIN Schwindel 8cda9a1a-a46f-4510-8872-d49bd4bc596e
A1 MAIN Fingerbeschwerden 704dc839-0de0-4797-b78b-1e6e488a47c7

A1 RELATED Schwarzer Stuhl/Blut im Stuhl 0884bccb-6582-4622-8581-5e970ede1ecb

What I expected from the ARRAY_AGG function was the following result:

TOKEN TYPE SYMPTOM_TEXT SYMPTOM_CODE
A1 MAIN [Schwindel,Fingerbeschwerden,Mund-/Zungen-/Lippenbeschwerden,Durchfall] [8cda9a1a-a46f-4510-8872-d49bd4bc596e,704dc839-0de0-4797-b78b-1e6e488a47c7,83431d7a-3555-444e-a693-24a7111e782d,f028a1f4-214d-4f15-afda-8d2691912d5f]
A1 RELATED [Fieber,Schwarzer Stuhl/Blut im Stuhl] [1b5cc668-d357-43af-a863-799ebe288ffc,0884bccb-6582-4622-8581-5e970ede1ecb]

So my question would be two-fold:
(1) Did I missunderstood the function and if not
(2) how do I get rid of the error-message?

I already checked the topics towards setting the parameter limits.single_field_size_bytes: to a higher value, but even setting it to 99.000 does not change the error-message.

We are running Dremio 24.3.2 on-premise.

Thanks in advance, Daniel
