Lambda NodeJS error: libcouchbase.so.2: cannot open shared object file: No such file or directory

Question

I get the error libcouchbase.so.2: cannot open shared object file: No such file or directory in my lambda when it tries to initalize

Running on Lambda using Couchbase and the Node SDK with external C bindings

---

These are the steps I do to package everything up:

1. Install libcouchbase rpm package in docker container
2. Copy across libcouchbase.so, libcouchbase.so.2 and libcouchbase.so.2.0.65 files into deployment package
3. Install couchbase npm package pointing to the .so files.
4. Use serverless framework to package and deploy to lambda

---

Here is a snippet of the commands I run to do so:

WORKDIR /lambda

RUN wget http://packages.couchbase.com/releases/couchbase-release/couchbase-release-1.0-6-x86_64.rpm
RUN rpm -iv couchbase-release-1.0-6-x86_64.rpm
RUN yum install -y libcouchbase-devel libcouchbase2-bin

RUN mkdir -p libs\
  && cp /usr/lib64/libcouchbase.so libs \
  && cp /usr/lib64/libcouchbase.so.2 libs \
  && cp /usr/lib64/libcouchbase.so.2.0.65 libs

RUN npm install couchbase --compile --couchbase-root=libs

The error I get is:

{
  "errorMessage": "libcouchbase.so.2: cannot open shared object file: No such file or directory",
  "errorType": "Error",
  "stackTrace": [
    "Module.load (module.js:565:32)",
    "tryModuleLoad (module.js:505:12)",
    "Function.Module._load (module.js:497:3)",
    "Module.require (module.js:596:17)",
    "require (internal/module.js:11:18)",
    "bindings (/var/task/node_modules/bindings/bindings.js:112:48)",
    "Object.<anonymous> (/var/task/node_modules/couchbase/lib/binding.js:213:36)",
    "Module._compile (module.js:652:30)",
    "Object.Module._extensions..js (module.js:663:10)"
  ]
}

Found the issue. Lambda has LD_LIBRARY_PATH set to /var/task/lib where I was putting the libraries in /var/task/libs
