pulsar-manger:v0.4.0 couldn't link pulsar:2.8.0

I run pulsar and pulsar-manager via docker-ce:24.0.2.
Here is pulsar start command:
```shell
docker run --restart always --name pulsar -it -p 16650:6650 -p 16651:8080 -e "JAVA_TOOL_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+UseZGC" -v /data/pulsar/data:/pulsar/data -d apachepulsar/pulsar:2.8.0 bin/pulsar standalone
```
I test this pulsar cluster successful.
And here is pulsar-manager start command:
```shell
docker run --restart always --name pulsar-manager -it -p 19527:9527 -p 17750:7750 -e SPRING_CONFIGURATION_FILE=/pulsar-manager/pulsar-manager/application.properties -v /data/pulsar-manager/bkvm.conf:/pulsar-manager/pulsar-manager/bkvm.conf --link pulsar -d apachepulsar/pulsar-manager:v0.4.0
```
I just changed `bkvm.conf` in line 1st: `bkvm.enabled=true`.
I can't login pulsar-manger in site http://localhost/ui/index.html. And this is [pulsar-manager.log](https://github.com/apache/pulsar-manager/files/13303054/pulsar-manager.log).
