extent analysis

TL;DR

The issue with meta tags being rendered in the HTML body instead of the head can be addressed by investigating the Next.js configuration and the code that generates the meta tags.

Guidance

  • Review the next-generate-metadata code to ensure that meta tags are being generated correctly and appended to the HTML head.
  • Verify that the next version 15.5.3 is correctly configured and that there are no overrides or custom configurations that could be causing the issue.
  • Test the code with an earlier version of next, such as 15.1.8, to confirm that the issue is indeed related to the version change.
  • Check the HTML source to see if there are any other elements or scripts that could be interfering with the meta tags' placement.

Example

No specific code example can be provided without further information about the next-generate-metadata code.

Notes

The issue seems to be related to a change in the next version, as it is not present in version 15.1.8 but appears in versions from 15.2 onwards.

Recommendation

Apply a workaround by modifying the code that generates the meta tags to ensure they are correctly appended to the HTML head, as the issue is likely related to a change in the next version.
