KB-2298 AI Skill fails to import and/or export

Symptoms

When importing or exporting an AI Skill, users may encounter one or more of the following symptoms:

Using Compare & Deploy with AI Skills can result in a 504 error during export.

The deployment.log for the package will contain 504 errors.

aiSkill <id> <uuid>: The data for aiSkill [id=<id> uuid=<uuid>] could not be retrieved for export. Cause: java.lang.RuntimeException: com.appiancorp.rdo.client.invoker.ApiException: <html>

(APNX-1-4071-002)

If the AI Skill is successfully exported manually, the following error is observed upon import inside the deployment.log when the Inspect feature is used:

YYYY-MM-DD HH:MM:SS.mmm DEBUG aiSkill <uuid> Creating object.
YYYY-MM-DD HH:MM:SS.mmm ERROR aiSkill <uuid> An error occurred while creating aiSkill [uuid=<uuid>]: java.lang.RuntimeException: com.appiancorp.rdo.client.invoker.ApiException: (APNX-1-4071-007)

com.appiancorp.ix.ConsumerException: type=aiSkill, srcId=<srcId>, dstId=null, cause=java.lang.RuntimeException: com.appiancorp.rdo.client.invoker.ApiException: , level=ERROR, object=com.appiancorp.object.remote.aiskill.AiSkillRemoteHaul@22bbc641

Cause

Each AI Skill takes an estimated time of 4 minutes to export, but SAIL synchronous requests are cancelled by the web server after 5 mins, which results in a web server timeout indicated by the 504 error code.
