Property transform not working on platform 8.5.2

Hello,

After installing Platform-Analytics, Property Transform is not working. 

My environment is:

- Virtual Machine 1

     - THW Platform: 8.5.2

     - SSL:443

     - Autogenerated certificate

- Virtual Machine 2

     - Analytics Server: 8.5.2

          - Connected to the platform and working

    - Platform-Analytics: 8.5.1

          - RabbitMQ and Apache Flink from the installer

          - Erlang 21.0

          - The installation summary said that everything went OK and Things were created

I have the following error in configuration.log: (attached)

2020-09-17 08:59:41 [pool-1-thread-1] ERROR c.t.a.d.c.FlinkStatusCheck - Error while checking status of Flink cluster

In the flink1-4 log file, there is no error printed (see attached), the only thing that seems strange is the message "JAVA HOME: (not set)" because in /etc/environments 

            export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_141/

is set.

I can't find any reference related with the error I am getting with flink in the knowledge database.

Thanks in advance for your help.

Olatz.
