Steps to reproduce

Run the following code

const preprocessLaTeX = (content) => {
        // Replace block-level LaTeX delimiters \[ \] with $$ $$
        const blockProcessedContent = content.replace(
          /\\\[(.*?)\\\]/gs,
          (_, equation) => `$$${equation}$$`,
        );
        // Replace inline LaTeX delimiters \( \) with $ $
        const inlineProcessedContent = blockProcessedContent.replace(
          /\\\((.*?)\\\)/gs,
          (_, equation) => `$${equation}$`,
        );
        return inlineProcessedContent;
    };


{text && text.length > 0 &&
                            text.map((message, index) => (
                                <div key={index} className="markdown" id="bot-msg">
                                    <ReactMarkdown
                                        remarkPlugins={[remarkMath]} 
                                        rehypePlugins={[rehypeRaw, rehypeKatex]}
                                        components={{
                                            img: ({node, ...props}) => <img style={{maxWidth: '100%'}} {...props} />
                                        }}
                                    >
                                        {preprocessLaTeX(message)}
                                    </ReactMarkdown>
                                </div>
                            ))
                        }

Thanks!

Next step, when raising an issue, is to try to make your reproduction smaller.
As small as can be.
Remove everything that’s not related to the error.
I am quite sure that an _propertyInformation.hastToReact error does not come from your img component. Or from preprocessLaTeX.

Then, search through the existing issues. If you look for hastToReact here, you will find: #747

So, it seems that this error occurs because you use an older bundler with bugs: likely Parcel. Can you confirm this is the case?

Yes, I checked the issue disappeared by manually doing

npm install property-information

and

import 'property-information'
in my component.

Hi! Thanks for taking the time to contribute!

Because we treat issues as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.

Thanks,
