While starting the TM and Control Plane profiles in APIM 4.0.0 U2 pack level 46, after optimizing it gave FileNotFound errors for the files at repository/deployment/server/synapse-configs/default/inbound-endpoints/ and after adding the 4 files, the issues are solved.

sh api-manager.sh --optimize -Dprofile=control-plane

hi, same here. Any fix or workaround ?

[damoebius]

Ok, i get it.

TIL :

• running sh api-manager.sh --optimize -Dprofile=control-plane the first time worked but failed the second time with error above
• running sh api-manager.sh -Dprofile=control-plane the first time failed

What's worked for me

1. running sh profileSetup.sh -Dprofile=control-plane once before launching anything else
2. running sh api-manager.sh -Dprofile=control-plane always works

Documentation isn't really clear : https://apim.docs.wso2.com/en/latest/install-and-setup/setup/distributed-deployment/deploying-wso2-api-m-in-a-distributed-setup/
