Cannot install content pack with EventDefinition that uses Default Stream

[mpfz0r]

If the EventDefinition contains the default stream, I get

Caused by: org.graylog2.contentpacks.exceptions.ContentPackException: Missing Stream for event definition

EventDefinitions with streams other than the default one, however work.

Could this be an oversight of my change from #6873 ?

[kmerz]

@pschichtel no you made a foundation for being able to use default streams. But it was not implemented yet here :/

FYI: A workaround is to delete the reference to the default content pack 00000000001. Thank you @mpfz0r for the tip!

As a note, we're seeing a lot of cases like this in support where either the customer can't import a content pack, or we cannot due to this bug. HS-455718737 and HS-439847458 are two recent examples. Getting some traction on this would be a huge help.

Just got a new ticket regarding this exact same issue: HS-1055582473. Graylog v4.3.5.

This also seems to be an issue for content packs with Dashboards containing widgets that use a Stream:
