I have used a .tsx file with the @astro/react integration in Astro. The syntax within is entirely standard. However, when I try to build it, I encounter an error in the JSX part of the React return statement (no errors are displayed in VSCode), and I am unable to complete the build. How can I fix this?
#When building, an error occurs saying 'Type 'Element' is not assignable to type 'ReactPortal'.

Hi @lofty ermine. 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 provided in the extracts, it seems like you're encountering a type error related to React integration in Astro. This issue has been reported in the Astro GitHub issues, such as issue #9451 (https://github.com/withastro/astro/issues/9451) and issue #3945 (https://github.com/withastro/astro/issues/3945).
However, the specific error you're encountering, 'Type 'Element' is not assignable to type 'ReactPortal', is not directly addressed in the provided extracts.
It's worth noting that these type errors could be due to a variety of reasons, such as incorrect usage of JSX syntax, issues with TypeScript configuration, or problems with the specific versions of Astro or React you're using.
Without more specific information or code examples, it's difficult to provide a definitive solution. I would recommend checking your JSX syntax and TypeScript configuration, and ensuring you're using compatible versions of Astro and React.
If the issue persists, consider raising an issue on the Astro GitHub page (https://github.com/withastro/astro/issues) for more targeted assistance.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

I'm writing JSX as the return value of a React component, but its contents are regular HTML, which seems to be causing type errors. These errors are occurring for each tag individually... I've figured out that astro check is the cause, but I don't know how to resolve it.

Let me check the knowledge base for you. One moment! :books:
Based on the provided extracts, it seems like you're encountering type errors when returning HTML content from a React component in an Astro project. This issue has been reported in the Astro GitHub issues, such as issue #3945 (https://github.com/withastro/astro/issues/3945) and issue #7499 (https://github.com/withastro/astro/issues/7499).
In Astro, JSX is handled differently compared to traditional React. Astro uses its own JSX syntax, which is HTML-first. This means that writing direct JSX in .astro files might cause issues, especially if you're trying to use React-specific JSX syntax.
One potential solution could be to ensure that you're using Astro's JSX syntax correctly. For example, in issue #7499 (https://github.com/withastro/astro/issues/7499), a user found that the issue occurred when using a head element in a custom component. They were able to resolve the issue by returning the head element as a string, like so:
function Demo() {
return '<head></head>';
}
