Wrong GRPC version in POM file on Maven Central / Library does not work in a Maven project

[Equiphract]

This library will not work when using it in a Maven project. I do get the following stack trace when trying to open a session with an ImmuDB instance:

I have found the error to be located in the library's POM file on Maven Central, specifically these three dependencies seem to cause the issue:

<dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-protobuf</artifactId>
      <version>1.44.1</version>
      <scope>runtime</scope>
</dependency>
<dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-netty</artifactId>
      <version>1.44.1</version>
      <scope>runtime</scope>
</dependency>
<dependency>
      <groupId>io.grpc</groupId>
      <artifactId>grpc-stub</artifactId>
      <version>1.44.1</version>
      <scope>runtime</scope>
</dependency>

When I override the version number with 1.55.1 for each of those dependencies in my own project's POM, my application is able to communicate with ImmuDB.

Hi,

I have also encountered this problem (and the solution works for me as well). I see that the version of the grpc dependency has already been updated (by @ostafen ), but there has been no release so far. Are there any plans to publish a release with this change?
