Hi @jurosh . Sorry for the late reply. Will you be able to verify following process work? Setting up dynamodb local directly

[jurosh]

In meanwhile I am running database in Docker, without any issues. But I may try this later.

@AshanFernando seems yes, no error when running jar from site.

>java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb
Initializing DynamoDB Local with the following configuration:
Port:   8000
InMemory:       false
DbPath: null
SharedDb:       true
shouldDelayTransientStatuses:   false
CorsParams:     *

Happens to me as well. Looks like the problem with interrupted install process. This can easily happen due to low jasmine.DEFAULT_TIMEOUT_INTERVAL + installing dynamodb right before the tests. Increasing of jasmine.DEFAULT_TIMEOUT_INTERVAL helps.

No sense of testing the jar from the aws site, instead, you should test with your local dynamoLocal.jar in the dir .dynamodb of the serverless project home.

Test against with "java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb" to see what happens.

Probably this issue is caused by an interrupted download and worse still, when you re-run sls dynamodb install, it will remind you that "Dynamodb is already installed on path!" even it's a broken jar.

Prune that dir and run "sls dynamodb install" again! Hope that helps
