serverless-dynamodb-local: Unable to start DynamoDB Local process!

Any help/idea would be very much appreciated, I’m new to all this serverless thing and want to learn. Thank you in advance!

Actual Behaviour

I’m unable to start DynamoDB locally and general error: Unable to start DynamoDB Local process!, I followed the steps in multiple tutorials, none will make it start.

Expected Behaviour

DynamoDB should be running smoothly on port 8000

Steps to reproduce it

Running the commands “sls dynamodb install” and “sls dynamodb start -p 8000”

0.2.35 worked for me only after removing the latest version and then running through the complete setup again:

yarn remove serverless-dynamodb-local
yarn add serverless-dynamodb-local@0.2.35
sls dynamodb install

Also perhaps worth noting that if the java sdk isn’t installed, an error will occur with a link just to java and not the sdk and so installing it will not help. Google java sdk for latest versions/OS.

In case you want to use the latest version (0.2.36) check this issue https://github.com/99xt/serverless-dynamodb-local/issues/195.

after upgrading running the install command like this fixed the issue for me (on MacOS) sls dynamodb install --localPath ./bin

this worked for me:

is exist error with version 0.2.36 serverless-dynamodb-local, then install:

Steps:

npm install serverless-dynamodb-local@0.2.35
sls dynamodb install
sls offline start

Guys, I’ve tried all solutions but didn’t work for me, what works is installing JRE (Java Runtime Engine). DynamoDB local requires Java Runtime Engine version 6.x or newer. Make sure u have installed JRE (Java Runtime Engine) on your machine.

don’t forget to run “sls dynamodb install” before running “sls offline start”

I confirm above worked… used npm …

@jeremiahlukus that would have been tough since I had no idea what the problem was beyond “the new version is broken” and it feels like it would’ve been bad form for a PR to just say “delete everything since the last version” 😉

Luckily for both of us @shalithasuranga already has submitted a pull request, #215, which I think aims to fix this issue via the solution found in issue #195 . Now we’ll just wait and see if it gets merged in and released to NPM…

dynamodb/utils.js:absPath() in the dynamodb-localhost@0.0.5 package caused this issue

“0.2.36” is using older version 0.0.5 of dynamodb-localhost, whereas “0.2.35” is usingdynamodb-localhost@0.0.6

the workaround would be update your package.json

  "resolutions": {
    "dynamodb-localhost": "0.0.7"   // or "0.0.6"
  }

I fixed the problem with installing openjdk. I missed reading plugin requirements. 😕

ghost on Apr 11, 2019

Please try new version 0.2.37. The issue was fixed

shalithasuranga on Mar 30, 2019

@zackzachariah #215 will be merged and npm module will be updated asap 👍

shalithasuranga on Mar 29, 2019

It was something else on my side. The utils.absPath() in dynamodb-localhost always does this:

return path.dirname(__filename) + "/" + relPath

When I launch sls dynamodb install from the VS code terminal, the path passed down is already an absolute path. The install command then just silently does nothing.

I fixed the absPath() to be a little more intelligent but it’s already fixed in the dynamodb-localhost as of 0.0.6. The latest version of serverless-dynamodb-local seems to install 0.0.5. I forced the latest using yarn’s resolutions and it now installs and starts just fine:

  "resolutions": {
    "serverless-dynamodb-local/dynamodb-localhost": "0.0.7"
  }
