I'm having this Problem for Days and I don't know how to fixing it.

Running on Docker swarm with just the basic instructions in the readme and getting [ Failed ] failed to init request tracer, error failed to init tracer, error lookup jaeger-agent.faasflow on 127.0.0 .11:53: no such host

When invoke flow, I got request failed to be processed.

I don't know how to fixing this problem?

I got deploy/function logs look like

[ Failed ] failed to execute request

I am a student, and your help means a lot to me. @s8sg @pasdam
I was trying out faas-flow-example, and take Sync-chain for example. As the following figure shows, I successfully deployed them to OpenFaas API gateway, and I can invoked the function. But with failed information.

I checked the logs. basically connection refused error. But I can invoke func1, func2 in the ui. Why can't I invoke them in sync-chain function???
