Getting error to start application

[aimanskie]

Hi Community,

Need help regarding this error when i tried to remove addons. Initially i removed exo-onlyoffice only and that was fine, exo was running. However, when i added more, from the logs uninstalling the addons was successful but i am getting this error like so when i added more in the list.

| ERROR | Called stop() on failed component [StandardEngine[Catalina].StandardHost[localhost]] to trigger clean-up but it failed too [org.apache.catalina.util.LifecycleBase<main>]

Hi @aimanskie
FYI , some addons are related and one depends from the other.
seeing a part of the exception in the attached screenshot, I think the problem is related to Jitsi addon, which depends on exo-webconferencing addon .
You need to remove it too if you do not intend to have video calls in your platform, otherwise, you will have to reinstall exo-webconferencing.

Thanks! I think that did resolve that error. However, there's another error even when i removed the exo-web-conferencing addon all together.

Don't hesitate to post full startup logs, and your context.
