Setting up a connection to Dynamo

[bryxli]

I'm trying to create a command that accesses Dynamo with a script I wrote. This is how I imported it:
const DynamoDB = require('../DynamoDB')

I can access the database in a test Node.js file:
node testDynamo.js

However, when I import the file into my command located in the commands folder, sam deploy hangs on CreateCommandsInvoker.

I have read this discussion post, but I am unsure where to begin to import DynamoDB.js into the resource.

Hi there,

did you check the logs of CreateCommandsInvoker? What do they say?

Also, you should probably share a minimal, complete and reproducible example of your code that causes the problem so we can dig deeper into your issue.

My table is set up with the partition key as the guild_id. I have also tried to do a fresh build (deleting the build from AWS and redeploying it).

DynamoDB.js

const { DynamoDBClient, GetItemCommand } = require('@aws-sdk/client-dynamodb');
const REGION = "us-east-1";
const tableName = 'table_name';

ddbClient = new DynamoDBClient({ region: REGION });

async function getGuild(guild_id) {
  const params = {
    TableName: tableName,
    Key: {
      'guild_id': {'N':guild_id}
    }
  };

  const data = await ddbClient.send(new GetItemCommand(params));
  return data.Item;
}

exports.getGuild = getGuild;

I tested this by manually inserting my test server id into the table and checking if I get a return.

helpCommand.js

const {SlashCommand} = require('slash-create');
const DynamoDB = require('../DynamoDB')

module.exports = class HelpCommand extends SlashCommand {
    constructor(creator) {
        super(creator, {
            name: 'help',
            description: 'display help menu',
            guildIDs: ['1016953904644247632']
        });
        this.filePath = __filename;
    }

    async run(ctx) {
        let result= '';
        try{
            const data = await DynamoDB.getGuild(String(ctx.guild.id));
            if (typeof data !== 'undefined')
                result = 'success';
        } catch (err) { console.log(err); }

        return result;
    }
};

I have not made any changes to the template file other than adding AmazonDynamoDBFullAccess policy to the two functions. This is what I see on CloudWatch.
