Hi @Nandish. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information available, it seems like your issue might be related to missing dependencies or incorrect module handling in your deployment environment. Here are a few steps you can take to resolve the ReferenceError: require is not defined error: 1. Install Missing Dependencies: Ensure that all necessary dependencies, such as graphql and graphql-tag, are installed. There is a known issue where the graphql module might be missing, causing build failures. You can install the graphql-tag package as a dev dependency as a workaround:

   npm install graphql-tag --save-dev

   npm install graphql-tag --save-dev

This was suggested by the support staff in a Discord support thread:

Trusted Support Staff 20: Hello Community Member 185 thanks for the report! We'll fix it, in the meantime, you can install graphql-tag package as dev dependecy as a workaround (source (https://discord.com/channels/837692625737613362/1203779575335624725)).

2. Check for Type Declarations: Ensure that the graphql module and its type declarations are correctly installed. A similar issue was reported where the build failed due to missing type declarations for graphql:

Type error: Cannot find module 'graphql' or its corresponding type declarations (source (https://github.com/refinedev/refine/issues/5852)).

3. Review Your Dockerfile: If you are using Docker for deployment, make sure your Dockerfile is correctly set up to install dependencies only when needed. Here is an example snippet from a Dockerfile:

   FROM base AS deps

   FROM base AS deps

This ensures that dependencies are installed in the correct stage of the build process (source (https://discord.com/channels/837692625737613362/1181321409146925066)). 4. Handle GraphQL Errors: If you are using a custom GraphQL client, ensure that it correctly handles errors. Here is an example of how to handle GraphQL error responses:

   const customNHost = {
     graphql: {
       request: (query, variables) => {
         return nhost.graphql.request(query, variables).then((result) => {
           if (result.error) {
             throw result.error;
           }
           return result;
         });
       },
     },
   };

   const customNHost = {
     graphql: {
       request: (query, variables) => {
         return nhost.graphql.request(query, variables).then((result) => {
           if (result.error) {
             throw result.error;
           }
           return result;
         });
       },
     },
   };

This ensures that any errors from the GraphQL server are properly thrown and can be handled accordingly (source (https://github.com/refinedev/refine/issues/1794)). By following these steps, you should be able to resolve the ReferenceError: require is not defined error in your Amplify deployment. If the issue persists, consider checking the Amplify documentation or reaching out to their support for more specific guidance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I heard that web browser don't have "require" how to workaround this ? I tried webpack configuration, but it is not working as expected
