Spring Cloud GCP连接Firestore模拟器时遭遇INTERNAL: http2 exception错误的排查与解决请求

大家好，我目前正在本地使用Firestore模拟器测试Spring应用，通过com.google.cloud:spring-cloud-gcp-data-firestore依赖来配置数据库连接。

我的依赖配置如下：

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>spring-cloud-gcp-data-firestore</artifactId>
</dependency>

本地配置文件内容：

spring.cloud.gcp.firestore.emulator.enabled=true
spring.cloud.gcp.firestore.emulator.host-port=localhost:8082
spring.cloud.gcp.firestore.emulator.project-id=local-project

我已经完成模拟器的安装，启动命令为：gcloud emulators firestore start --host-port=localhost:8082，模拟器能正常启动，但当我调用Repository的保存方法时：

myObjectRepository.save(myObjectLocal).block();

会抛出异常，核心报错信息如下：

Caused by: io.grpc.StatusRuntimeException: INTERNAL: http2 exception

需要说明的是，当我配置连接远程GCP官方Firestore数据库时，代码可以正常运行，能够成功保存myObject。有没有朋友能帮忙排查下模拟器连接的问题？
