zihaozeng0021 opened a new issue, #2262:
URL: https://github.com/apache/age/issues/2262
### Configuration
AGE Version: `apache/age:latest` (pulled 2025-12-07)
Operating System: WSL2 – Ubuntu 24.04.1 LTS
Installation Method: Docker
---
### Steps to reproduce
1. Start AGE via Docker
```
docker run \
--name age \
-p 5455:5432 \
-e POSTGRES_USER=postgresUser \
-e POSTGRES_PASSWORD=postgresPW \
-e POSTGRES_DB=postgresDB \
-d \
apache/age:latest
```
2. Connect with psql
```
PGPASSWORD='postgresPW' psql -h localhost -p 5455 -U postgresUser -d
postgresDB
```
3. Run the following query
```
CREATE EXTENSION IF NOT EXISTS age;
LOAD 'age';
SET search_path = ag_catalog, "$user", public;
SELECT create_graph('test_graph');
SELECT *
FROM cypher('test_graph', $$
WITH 1 AS x
WITH count(x) AS skipAmount
UNWIND [1, 2] AS a
RETURN a
SKIP skipAmount
$$) AS (a agtype);
```
---
### Expected behaviour
The query runs sucessfully
### Actual behaviour
The query failed with the message:
```
ERROR: argument of SKIP must not contain variables
LINE 7: SKIP skipAmount
```
Key points:
1. There is a contradiction between this result and the documentation.
2. The
[documentation](https://age.apache.org/age-manual/master/clauses/skip.html)
states `SKIP` accepts any expression that evaluates to a positive integer.
3. Expressions are combinations of variables and numbers, and the
`skipAmount` is a variable that is always 1 (a positive integer). However, the
results state that the argument of `SKIP` must not contain variables.
