Error: DynamoDB Network Error: self signed certificate in chain


Explanation: DynamoDB SDK/CLI has a problem negotiating SSL with AWS' servers.

Troubleshooting steps:

  • If you're running this command behind a firewall, make sure it's not blocking for modiyfing requests to the AWS. Try disabling the firewall and try again
  • If you're using Node.js, you can try setting NODE_TLS_REJECT_UNAUTHORIZED environment variable to 0.
  • Disable SSL (not recommended)
  • If you're using Node.js, you might also want to import the certificate manually:
    const https = require('https');
    const fs = require('fs');
    const customAgent = new https.Agent({ ca: fs.readFileSync('/etc/ssl/path/to/your/certificate/myCustomCA.pem')});
      httpOptions: { agent: customAgent }
