Failed to bind properties under 'grpc.client.port'

[Jouda-Hidri]

I am having the following error when deploying on k8s (locally all good, even when using docker)

Description:
Failed to bind properties under 'grpc.client.port' to net.devh.boot.grpc.client.config.GrpcChannelProperties:
    Reason: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [net.devh.boot.grpc.client.config.GrpcChannelProperties]
Action:
Update your application's configuration

This is my config

spring.application.name=k8scronjobs
# Enable Spring Batch schema initialization
spring.batch.jdbc.initialize-schema=always

# Database connection configuration
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.datasource.initialization-mode=always

spring.jpa.hibernate.ddl-auto= update


spring.batch.job.enabled=false

grpc.server.port=9090

I am using

• 'org.springframework.boot' version '3.4.3'
• 'net.devh:grpc-spring-boot-starter:3.1.0.RELEASE'
