I am attempting to import the amazon javascript sdk in to my Mendix 9.3 app. I am working with cognito functions and want to build a login solution using the SDK and a JSA in my app. My trouble, so far, is with importing the SDK into the app. I did an npm install aws-sdk in my /javascript/[module]/actions folder to bring in the library. I am getting compilation errors below. I get the below error when trying to deploy this to the Mx cloud. I see from a couple of forum posts that something is not being referenced properly. It looks like there's a call to util.js in the folder /javascriptsource/core/actions/node_modules/aws-sdk/lib but because the reference is not stating ./util but just calling util, the system is assuming it is referencing a module and is looking for a node_module folder in the lib folder. ERROR: An error occurred while compiling JavaScript actions [webpack-cli] ModuleNotFoundError: Module not found: Error: Can't resolve 'util' in '/srv/cloud/slots/tr10000/deploy/data/tmp/301602a1-c050-4288-8b8f-dcc286ff3780/src/javascriptsource/core/actions/node_modules/aws-sdk/lib' Did you mean './util'? Requests that should resolve in the current directory need to start with './'. Requests that start with a name are treated as module requests and resolve within module directories (node_modules). If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too. BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default. This is no longer the case. Verify if you need this module and configure a polyfill for it. If you want to include a polyfill, you need to: - add a fallback 'resolve.fallback: { "util": require.resolve("util/") }' - install 'util' If you don't want to include a polyfill, you can use an empty module like this: resolve.fallback: { "util": false } at /srv/cloud/slots/tr10000/deploy/data/tmp/9.3.0.22930/modeler/tools/node/node_modules/webpack/lib/Compilation.js:1762:28 at
