This is the RegionConfig.js file

import { __assign } from "tslib";
export var REGION_ENV_NAME = "AWS_REGION";
export var REGION_INI_NAME = "region";
export var NODE_REGION_CONFIG_OPTIONS = {
    environmentVariableSelector: function (env) { return env[REGION_ENV_NAME]; },
    configFileSelector: function (profile) { return profile[REGION_INI_NAME]; },
    default: function () {
        throw new Error("Region is missing");
    },
};
export var NODE_REGION_CONFIG_FILE_OPTIONS = {
    preferredFile: "credentials",
};
export var resolveRegionConfig = function (input) {
    if (!input.region) {
        throw new Error("Region is missing");
    }
    return __assign(__assign({}, input), { region: normalizeRegion(input.region) });
};
var normalizeRegion = function (region) {
    if (typeof region === "string") {
        var promisified_1 = Promise.resolve(region);
        return function () { return promisified_1; };
    }
    return region;
};

I'm facing the error: Uncaught (in promise) Error: Region is missing

Deployment: npm run dev or yarn dev

Hi @sriharshini22 since you didn't fill in the intake form its difficult for us to understand what the issue is.

The error specifies that you are not providing are a region when setting the config on the client.

Are you able to share your actual code?

Thanks, Ran~
