Issue Summary

This is reproducible on Data Center: (yes) / (no)

We got a ticket from where the partner mentioned getting 500 Internal Server Error: "{"statusCode":500,"message":"java.lang.NullPointerException: null"}" on calls to /rest/api/content/1135050765/history/15/macro/id/.

When checking for the available contentid, we noticed that related to contentId=1135050765, there are only available versions 6 (set current) and 1 (set as a draft), as can be seen below:

contentid,hibernateversion,contenttype,title,lowertitle,version,creator,creationdate,lastmodifier,lastmoddate,versioncomment,prevver,content_status,pageid,spaceid,child_position,parentid,messageid,pluginkey,pluginver,parentccid,draftpageid,draftspacekey,drafttype,draftpageversion,parentcommentid,username

However, since they’re trying to access something that doesn't exist, instead of a 500 response code, it's not expected that it would bring a 400 Bad Request or even a 404 Not Found error.

This is not the first case that the partner is reporting this kind of error message; however, we could see that this time, the atlassian/atlassian-connect-spring-boot is already under its last version.

Steps to Reproduce

1. N/A

Expected Results

According to our knowledge and confirmation obtained from the engineering team that analyzed the case, a 404 error was expected to occur.

Actual Results

The below exception is thrown in the logs:

stack: java.lang.NullPointerException: Cannot invoke "com.atlassian.confluence.core.ContentEntityObject.getBodyAsString()" because "content" is null
2com.atlassian.confluence.api.impl.service.content.ContentMacroServiceImpl$MacroInstanceFinderImpl.internalFetchByMacroId(ContentMacroServiceImpl.java:130)

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
