[BUG] Dependency Declaration Flowise Build Process

[seb-tc]

Describe the Bug

During the build process of the Flowise project, two main issues are encountered. First, the babel-preset-react-app package is importing the @babel/plugin-proposal-private-property-in-object package without declaring it in its dependencies. Second, the langchain/dist/util/bedrock module cannot be found, causing errors in AWSChatBedrock.ts and AWSBedrock.ts.

To Reproduce

Steps to reproduce the behavior:

1. Clone the Flowise Main branch from the repository.
2. Run yarn install to install dependencies.
3. Run yarn build to build the project.
4. See the error messages related to babel-preset-react-app and langchain/dist/util/bedrock.

Expected Behavior

The build process should complete without any errors, and all dependencies should be correctly declared and found.

Setup

• Installation: yarn start
• Flowise Version: Not provided
• OS: Not provided
• Browser: Not applicable

Additional Context

The error messages suggest two potential solutions. For the babel-preset-react-app issue, adding @babel/plugin-proposal-private-property-in-object to the project's devDependencies might resolve the problem. For the langchain/dist/util/bedrock issue, ensuring that the langchain package is correctly installed and that the path to the bedrock module is correct might solve the issue.

flowise-ui:build: One of your dependencies, babel-preset-react-app, is importing the
flowise-ui:build: "@babel/plugin-proposal-private-property-in-object" package without
flowise-ui:build: declaring it in its dependencies. This is currently working because
flowise-ui:build: "@babel/plugin-proposal-private-property-in-object" is already in your
flowise-ui:build: node_modules folder for unrelated reasons, but it may break at any time.

flowise-ui:build: babel-preset-react-app is part of the create-react-app project, which

flowise-ui:build: your devDependencies to work around this error. This will make this message

Renaming these two node files with .OLD (in green) temporarily removing them from the build path will let the server build and initiate again.
