I have configured my squid proxy to send the logs to Elasticsearch 7.17.6, everything is working fine, except the USER mapping.

The string expect is DOMAIN/USER, the ELK recieves it correctly on original message but then on mapping I just see DOMIN, /USER is missed.

 ![Screenshot_35](https://us1.discourse-cdn.com/elastic/original/3X/c/3/c309977b9f82c0bfb990a523a8872cb4a44a57c7.png)

The field type is configured as keyword in mapping and index patterns.

Anyone can help me to solve this issue.

Thanks in advance

Best regards

Problem fixed

In grok i must use

```
(%{DATA:squid.proxy.user}|-)

```

instead of

```
(%{USER:{DATA}|-)

```
