problem running email-a-poem sample

[codefromthecrypt]

I'm trying to use the email-a-poem sample with ollama. I tried to switch the dep and even add a property for the unused openapi key. However, if I do mvn quarkus:run from the email-a-pom dir, it crashes for a similar reason. Any idea what I'm doing wrong? My goal is to test otel and this seems like the only example integrated with it.

$ mvn quarkus:run

Hi,

I just tried exactly that and it worked without issue.

Keep in mind that if you want to test the OTel stuff, you need to start the sample with mvn quarkus:dev -Dobservability (which brings in the observability related Quarkus extensions).

[geoand]

@codefromthecrypt do you mind zipping the sample and adding it here if it continues to missbehave?

[codefromthecrypt]

So, I'm getting closer, and bear in mind I do not want to run the lgtm stack, that's why I was using run. I want to verify the traces with my own collector. When I run from top-level and then do a full build followed by quarkus:run, the server starts, and the form presents on :8080, but it has "Failed! Have you started the mock mail container?" in it. any ideas?

[codefromthecrypt]

ps in above the collector works, just the app is busted due to the mock mailer somehow

[geoand]

So, I'm getting closer, and bear in mind I do not want to run the lgtm stack, that's why I was using run

Oh, nice!

I'll look at the mailer issue soon and get back to you, there might be some kind of bug with quarkus:run - it should work with quarkus:dev

[geoand]

Oddly enough the error is happening in the browser (trying to figure it out now). If you do:

curl http://localhost:8080/email-me-a-poem

things should work

[geoand]

Oh, now I see why the browser fails...

When the application is run with quarkus:run, it listens on all network hosts, so Quarkus prints:

Listening on: http://0.0.0.0:8080

When you try to use that in the browser, you get a CORS error when clicking on the button.

If you instead use http://localhost:8080 everything works.

Let me see if non-existent JS skills can address the problem.

[geoand]

https://github.com/quarkiverse/quarkus-langchain4j/commit/0f7746a0a9cc21108e65caad615b0175d251aaec fixes the issue :)

[iocanel]

@codefromthecrypt It's been a while!

Your js console might reveal more information on what's going on, as the message implies that the HTTP request towards http://localhost:8080/email-me-a-poem barfed.

[geoand]

@iocanel problem fixed :)

[codefromthecrypt]

@iocanel I just can't quit you 🤠

[codefromthecrypt]

cool, it works. I think we need a clean build with the profile enabled first. If there are less steps we can pare it down

This is https://github.com/ymtdzzz/otel-tui and I am their ⭐ promotor, btw.

not sure I needed the endpoint property but hey

Really really cool!

Yeah, I'm thinking about making the observability stuff enabled by default - the reason we haven't done it so far is because it results in the downloading of a large docker image, but I think we can live with that.

[geoand]

@brunobat WDYT about making https://github.com/ymtdzzz/otel-tui available as a dev-service?

[codefromthecrypt]

if it helps, this is some notes I have until I make a collection of demos somewhere. Also very soon otel-tui will work with zipkin, too (not sure that matters here)

services:
  otel-collector:
    extends:
      file: docker-compose.yml
      service: otel-collector
    image: ymtdzzz/otel-tui:latest
    stdin_open: true
    tty: true
    command: []
    volumes: []

---

Run otel-tui instead of collector

If you want to view a text terminal UI instead of the collector, you can use otel-tui like this:

Use docker-compose to run ollama and an otel-tui in the background:

docker-compose -f docker-compose.yml -f docker-compose-tui.yml up -d

Then, attach your terminal to the terminal UI like this:

docker-compose -f docker-compose.yml -f docker-compose-tui.yml attach otel-collector

To detach from otel-tui, use Ctrl-p Ctrl-q.

Finally, to tear down otel-tui and ollama, execute this:

docker-compose -f docker-compose.yml -f docker-compose-tui.yml down
