Node-rdkafka: Error: librdkafka++.so.1: cannot open shared object file: No such file or directory on Heroku

I am trying to get node-rdkafka set up on an application running in Heroku, and every time the application starts I get this error:

Error: librdkafka++.so.1: cannot open shared object file: No such file or directory at Object.Module._extensions..node (module.js:681:18) at Module.load (module.js:565:32) at tryModuleLoad (module.js:505:12) at Function.Module._load (module.js:497:3) at Module.require (module.js:596:17) at require (internal/module.js:11:18) at bindings (/app/node_modules/bindings/bindings.js:81:44) at Object.<anonymous> (/app/node_modules/node-rdkafka/librdkafka.js:10:32) at Module._compile (module.js:652:30) at Object.Module._extensions..js (module.js:663:10)

I have the application building and running just fin on my local machine. I know that librdkafka-dev and librdkafka1 are installed on the Ubuntu builds on Heroku by default, but I don't know what else to look at.

You have to use the Confluent librdkafk package.

Add this to your Aptfile:
:repo:deb [arch=amd64] http://packages.confluent.io/deb/4.0 stable main

Still having issues after doing this, but they are different issues and it looks like I'm closer.

I have the same issue with a docker container hosted on linux. I had to revert:

 node-rdkafka@^2.2.0:
-  version "2.3.1"
-  resolved "https://registry.yarnpkg.com/node-rdkafka/-/node-rdkafka-2.3.1.tgz#1c10b85c997243d50a14b09c03ee8f2370df8d56"
+  version "2.2.3"
+  resolved "https://registry.yarnpkg.com/node-rdkafka/-/node-rdkafka-2.2.3.tgz#05d8cafdbaf27bf1e8ef2b8e5bf39afb59a2e701"
   dependencies:

I also experienced this when I upgraded. My build ran and then I copied the assets over into the container. If you are able to run the install on the target server (or docker image) it works as it did in previous versions.
