Unable to Start the Fivetran Proxy Agent Service on Linux

Issue

When running systemctl start fivetran_proxy.service to start the Fivetran Proxy Service on Linux, the following error appears:

Unit configuration has fatal error, unit will not be started. /etc/systemd/system/fivetran_proxy.service:11: Neither a valid executable name nor an absolute path: ${HVR_HOME}/jre/bin/java

Environment

Connection option: Fivetran Proxy Agent
Operating system: Linux

Resolution

To resolve this issue:

Open the service file located at /etc/systemd/system/fivetran_proxy.service.
In the ExecStart directive, replace ${HVR_HOME} and any similar variables with the full absolute path to the executable. For example, replace:
```
ExecStart=${HVR_HOME}/jre/bin/java ...
```
with the following:
```
ExecStart=/home/fivetran/hvr_home/jre/bin/java ...
```
Apply the updated service configuration by running:
```
systemctl daemon-reload
```

Enable and start the service as root by running:

systemctl enable fivetran_proxy.service
systemctl start fivetran_proxy.service
systemctl status fivetran_proxy.service

Cause

Systemd doesn't expand shell-style environment variables, such as ${HVR_HOME}, in the ExecStart directive. As a result, systemd can't locate the Java executable when environment variables are used instead of absolute paths.
