timer-2117 opened a new issue, #2166:
URL: https://github.com/apache/age/issues/2166
**Describe the bug**
Using PostgreSQL version 16.6 and its corresponding age version 1.5.0,
importing a database using a CSV file is not possible when there is only one
attribute in the CSV file
**How are you accessing AGE (Command line, driver, etc.)?**
- psql
**What data setup do we need to do?**
```pgsql
...
select
load_labels_from_file('livejournal','Person','/import/ljournal-vertex.csv');
...
```
**What is the command that caused the error?**
```pgsql
select load_edges_from_file('livejournal','Knows9','/import/test1.csv');
SELECT * FROM cypher('livejournal', $$MATCH(a)-[r:Knows9]->(b) RETURN r $$)
as (a agtype);
```
```

**Expected behavior**
