Bug Report

Name	Severity	Example test case	Description
Potential incompatibility between @tailwindcss/[email protected] and [email protected]	Medium	Update tailwindcss to 4.1.12 and check if all Tailwind CSS classes are applied correctly in the frontend.	@tailwindcss/postcss is responsible for processing Tailwind CSS with PostCSS. The patch updates tailwindcss to 4.1.12, but @tailwindcss/postcss remains at version 4.1.11. This could lead to inconsistencies or unexpected behavior in the frontend, especially if [email protected] introduces new CSS functions or directives that are not recognized by @tailwindcss/[email protected]. This might result in styling issues where certain Tailwind CSS classes are not applied correctly.

Bug Report

Name	Severity	Example test case	Description
Potential incompatibility between @tailwindcss/[email protected] and [email protected]	Medium	Update tailwindcss to 4.1.12 and observe potential styling issues.	The vite plugin might not be fully compatible with the newer version of tailwindcss, potentially leading to styling issues or build errors.
Dependency conflict with react-json-view	High	Run npm install and observe the dependency conflict error.	The react-json-view dependency requires a React version that is incompatible with the project's React version, causing installation errors.
Build process timeout	Medium	Run npm install --force and observe the timeout error.	The npm install --force command timed out, indicating a potential issue with dependency resolution or the build process.

Bug Report

Name	Severity	Example test case	Description
Dependency Conflict	Critical	Run npm install in the frontend directory.	There is a dependency conflict between react (version 18.3.1) and react-json-view (which requires a version of react that is not 18). This prevents the frontend from being built, as npm install fails.
