Cannot find Flow/Processes via IPC

[AStollberger]

Hello there,

i have installed the gdt-server as a docker container, as descripted in the readme. Then I Provided a Datebase for the Dockercontainer and startet the GDT Server with the following Command:
docker run -p 3000:8080 -v $HOME/openLCA-data-1.4:/app/data --rm -d gdt-server -db myDatabase

When I try to get all Flows or Processes or any other Kind of Model via an IPC-Client in Python or Typescript, i get a response like the following in Typescript:

SyntaxError: Unexpected token 'N', "Not Found" is not valid JSON

and in Python:

When i Use a RestClient either in Python or Typescript i get a valid response.
Can you tell me what i am doing wrong? Do i have to enable the IPC functionality?
