Zainab-Saad opened a new issue, #1159:
URL: https://github.com/apache/age/issues/1159
**Describe the bug**
Updating properties of a vertex/edge (having a non-scalar value) with SET
plus-equal terminates the server
**How are you accessing AGE (Command line, driver, etc.)?**
Command Line
**What data setup do we need to do?**
Create 2 vertices with non-scalar property values
```
SELECT * FROM cypher('graph', $$
CREATE (n: A {map: {a : 1}}), (m: B {lst: [1, 2]})
$$) AS (result agtype);
```
**What is the command that caused the error?**
This query terminated the server (same for vertex with label `B`)
```
SELECT * FROM cypher('graph', $$
MATCH (n: A) SET n += {bool: true} RETURN n
$$) AS (result agtype);
```
**Expected behavior**
Should update the properties as shown
[here](https://github.com/apache/age/blob/master/regress/expected/cypher_set.out)
**Environment (please complete the following information):**
AGE master (This problem exists for other branches too)
**Additional context**
SET plus-equal works fine for scalar property values
```
SELECT * FROM cypher('graph', $$
CREATE (n: C {num : 1}) RETURN n
$$) AS (result agtype);
```
```
SELECT * FROM cypher('graph', $$
MATCH (n: C) SET n += {bool: true} RETURN n
$$) AS (result agtype);
result
