Apicurio throwing io.apicurio.registry.storage.ArtifactNotFoundException while uploading a new artifact

[nehasewda]

While trying upload a new artifact via Apicurio registry UI, getting io.apicurio.registry.storage.ArtifactNotFoundException.
Kindly help.

@nehasewda do you mind please adding some context here? More specifically:

• Apicurio Registry version
• Some steps with the operation you're trying to perform
• Example data in case you think it might be a problem with data format or something like that (e.g. artifactId is being sent as header)

Thanks

Sorry for the delay.

1. Apicurio image used - apicurio/apicurio-registry-kafkasql:latest-snapshot
2. Trying to upload an artifact with an ID "out-stream" with a valid json schema.
3. Got the following error "io.apicurio.registry.storage.ArtifactNotFoundException artifact with ID out-stream not found".

Strangely, I was able to upload the same mentioned artifact after few retries.

I don't suppose you still have any server logs? :) I'm not actually sure that will help, but it's always worth a look.

@carlesarnal when you have some bandwidth to look at this, could you analyze the Create Artifact flow when using KafkaSQL as the storage and see if you can determine how ArtifactNotFoundException could occur? That's obviously an unusual exception to get when creating an artifact.

@nehasewda were you using the UI for this?

Hi @EricWittmann ,

Actually, this issue is intermittent. Therefore, not able to fetch the server logs at this moment(successfully updating new artifact as of now).

And yes, I was using the UI to upload new artifacts.

[EricWittmann]

OK thanks @nehasewda - intermittent is the worst kind! We'll keep trying to analyze it, but if you experience it again and can get the server logs and any stack traces that appear in the browser, that would be super helpful. In addition, if it's possible to get a dump of the kafka topic, that would be even better. Something like this:

kafkacat -b localhost:9092 -t kafkasql-journal -Z -O -D \\n--message-delimiter--\\n -e -K \\n----\\n -J > kafkacat-output-2.log

If you have proprietary schemas in there I understand. But if not, that full export of all the messages in the topic would be amazing.

[nehasewda]

Sure @EricWittmann . I will keep a track and pass the information as soon as I encounter this again.
Thanks for the help.

@nehasewda I think we may figured out the root cause of this issue:

#1993

[EricWittmann]

We should have a blog post about this issue we can point you to soon.

[nehasewda]

@EricWittmann sure. Thanks!

[EricWittmann]

We are confident that this has been fixed in #2030
