Error on heroku meteor app - meteor

I deployed my web app on heroku with the following procedures given in this document: https://medium.com/#leonardykris/how-to-run-a-meteor-js-application-on-heroku-in-10-steps-7aceb12de234#.93vvydncs
Then my app was not running and the logs said that meteor needs node v 0.10.41 or above.
I changed my buildpack to - https://github.com/kevinseguin/heroku-buildpack-meteor.git as per the solution in Meteor requires Node v0.10.41 or later Error on heroku deployment.
Then I get the error:
2016-08-19T14:50:27.547793+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=dss-society.herokuapp.com request_id=c116c227-b93e-482f-b17e-ec198d65fcf6 fwd="182.64.121.74" dyno= connect= service= status=503 bytes=

Now I don't know what to do next. Need help.
My app url on heroku staging is: https://dss-society.herokuapp.com/
My config of heroku has MONGODB_URI, MONGOLAB_URI, and MONGO_URL, all having the same values. Also it has PAPERTRAIL_API_TOKEN and ROOT_URL which is set to https://dss-society.herokuapp.com
My meteor version is 1.3.4.1.
I hope to get some solution over this. Thanks


The buildpack you are using does not seem to work. Try and use:
https://github.com/AdmitHub/meteor-buildpack-horse
So:
heroku buildpacks:set https://github.com/AdmitHub/meteor-buildpack-horse.git
I've copied and replaced parts of the guide which you can find here:
https://github.com/JaySheombar/meteor-on-heroku


I experienced same issue last week. You can look for the specific reason by typing heroku logs --app <appname>. In most cases, it was because the version of node your buildpack uses is not aligned with the version of node meteor uses. For Meteor 1.4+, it uses node 4.5.0 so you may need a buildpack that installs the same version of node. I created a guide for it here.

Error when checking the service status In Nebula Graph

Install NebulaGraph
sudo rpm -ivh nebula-graph-3.3.0.el7.x86_64.rpm
Start NebulaGraph
sudo /usr/local/nebula/scripts/nebula.service start all
[INFO] Starting nebula-metad...

[INFO] Done
Run the following command to check the service status of NebulaGraph.
sudo /usr/local/nebula/scripts/nebula.service status all
The returned result is the following one, there is a problem in nebula-graphd. How do I deal with this issue?
[INFO] nebula-metad(33fd35e): Running as 29020, Listening on 9559
[INFO] nebula-graphd(33fd35e): Running as 29095, Listening on 9669

[WARN] See Manage Storage hosts:ADD HOSTS in https://docs.nebula-graph.io/
[INFO] nebula-storaged(33fd35e): Running as 29147, Listening on 9779

Best to my knowledge, starting from NebulaGraph 3.0.0, the Meta service cannot directly read or write data in the Storage service that you add in the configuration file. The configuration file only registers the Storage service to the Meta service.
You must run the ADD HOSTS command to enable the Meta to read and write data in the Storage service.

How can I deploy shiny in docker?

I have a shiny app that is running on an EC2 instance that I'd like to deploy in docker. Running the shiny app on localhost (so the EC2 instance) works fine, albeit it takes ~5 minutes to load.
However, I've been told to run the following command to get the website running:
sudo docker run --rm -p $PORT:1234 --mount type=bind,source=/mnt/compbio/jupyter_s3contents/web/dashboard,target=/srv/shiny-server/ --mount type=bind,source=/mnt/compbio/jupyter_s3contents/,target=/home/rstudio/compbio/ --mount type=bind,source=/var/log/shiny-server/,target=/var/log/shiny-server/ shiny
However, all I get is the following output, and it doesn't run beyond this point.
[2020-11-10T15:25:36.498] [INFO] shiny-server - Shiny Server v1.5.13.944 (Node.js v12.15.0)

I am new to docker, any idea what I am doing wrong here?

Unable to run shiny server pro in evaluation period

I am trying to deploy shiny server pro on a ubuntu 19.04 machine. I opted for the 45 days evaluation period where in Rstudio provides unrestricted access to shiny server pro features for the said period. But after setting up the server, I found out in the logs that my evaluation period had expired just after one day of use.
For setting up the server I followed the following steps:
Entered my details in the evaluation period form in this link https://rstudio.com/products/shiny-server-pro/evaluation/
I received a link in my mail which took me to the page which contains the commands to set up the R shiny pro server in ubuntu. This can be found here https://rstudio.com/products/shiny/download-commercial/ubuntu/
After following the steps,and changing the run_as parameter to my username in shiny-server.conf file I was able to get the server running. But found this in the logs:
[2019-10-15T14:05:28.424] [INFO] shiny-server - Shiny Server Pro v1.5.12.1023 (Node.js v10.15.3)

[2019-10-15T14:05:28.541] [ERROR] shiny-server - Your evaluation has ended. Please activate!
I tried the same steps on an EC2 instance, but ran into the same problem.

for anyone facing a similar issue kindly note that I was able to resolve the above error by raising a ticket to Rstudio who acknowledged the same and were kind enough to provide me with a new trial period key

*/
#import "bootstrap";
#import "bootstrap-sprockets";
#import "font-awesome";

is it possible to have more detail of what happened exactly maybe you can share your heroku logs.
Type => heroku logs --tail on terminal
Thanks

When you're running app on heroku you need to precompile your assets
Do the following:
In development.rb file put the below line:
config.assets.debug = false
and then run
RAILS_ENV=production bundle exec rake assets:precompile

You need to config Rails to serve static assets in production: config/environments/production.rb
config.assets.compile = true
Try this hope its help !
