No python application found - service-metrics-gatherer

[WaddyAU]

Hello, I am hoping someone can help me with this error I am getting on a new installation of Report Portal with Docker on Ubuntu 20.04. I have scoured the web for a fix and cannot find one.

This is what I am seeing in the Container log:

The error is from reportportal_metrics-gatherer_1 container.

Error: {"log":"--- no python application found, check your startup logs for errors ---\n","stream":"stderr","time":"2022-06-08T21:32:33.566627977Z"} {"log":"[pid: 7|app: -1|req: -1/1170] 127.0.0.1 () {28 vars in 294 bytes} [Wed Jun 8 21:32:33 2022] GET / =\u003e generated 21 bytes in 0 msecs (HTTP/1.1 500) 2 headers in 83 bytes (0 switches on core 0)\n","stream":"stderr","time":"2022-06-08T21:32:33.566660879Z"}

And from docker ps

download the latest repo, and exec: docker build -t reportportal/service-metrics-gatherer:local .

and modify the docker-compose.yml's image

Thank you @kisscelia . I have been on leave and will give it a try.

When you say modify docker-compose.yml's image I am unsure what you mean? Currently it is default.

Can you advise?

I mean that you can change the image to reportportal/service-metrics-gatherer:local which you build locally.

So, you can use the latest code.

I am also facing similar issue, and looks like this is the issue in metrics-gatherer code.

spawned uWSGI worker 1 (pid: 7, cores: 1) spawned uWSGI http 1 (pid: 8) Traceback (most recent call last): File "main.py", line 24, in from flask import Flask, Response File "/venv/lib/python3.7/site-packages/flask/init.py", line 14, in from jinja2 import escape ImportError: cannot import name 'escape' from 'jinja2' (/venv/lib/python3.7/site-packages/jinja2/init.py) unable to load app 0 (mountpoint='') (callable not found or import error) *** no app loaded. going in full dynamic mode ***

for this problem, i found following solution on stack over flow.

I think, the source code is updated. but the docker image was not. so we only have to rebuild the image and run.

@kisscelia Can you please let me know the branch or tag to pull and documentation to build the service.

Hi, @Erankur91

please pull the latest code: git clone https://github.com/reportportal/service-metrics-gatherer.git

cd service-metrics-gatherer
docker build -t reportportal/service-metrics-gatherer:local .

cd reportportal

and modify the docker-compose.yml file.

and then you can use the image that you build locally.

Maybe you can use the latest image in the docker hub.

It was built 9 days ago. but I don't try it......

As @Erankur91 said, quick solution from StackOverfow is to run: pip uninstall flask then pip install flask inside the container and after restart it is OK.

Hi @WaddyAU , @Erankur91, as i see you have found the solution, is the issue still actual or can be closed?

[WaddyAU]

@MaryiaRymarchyk : Thanks to everyone. The solution worked for me. Please close.
