I am trying to revalidate path via api route its not working. While from server action it works. I have a page that has a Post route handler via /api route and a delete action via server actions.

It looks like this

// API route
      await connectDB();
      const newDoc = new Doc({ title, url });
      const savedDoc = await newDoc.save();
      revalidatePath("/admin/documents");
      console.log("SAVED DOCUMENT:", savedDoc);
      return NextResponse.json(
        {
          message: "Successfully added new document",
        },
        { status: 200 },
      );

While I have defined my delete action like this

export const deleteDocument = async (id: string) => {
  const doc = await Doc.findById(id);
  if (!doc) throw new Error("Document couldn't found !");
  try {
    const res = await fetch(doc.url, {
      method: "DELETE",
      headers: {
        "X-Custom-Auth-Key": getAuthKeySecret(),
      },
    });

    if (res.ok) {
      try {
        await connectDB();
        await Doc.findByIdAndDelete(id);
        revalidatePath("/admin/documents");
        revalidatePath("/documents");
      } catch (err) {
        console.log(err);
      }
    }
  } catch (err) {
    console.log(err);
  }
};

While I add new documents it revalidates. But while I delete it doesn't.
NOTE: I am also using middleware to route to different language

  const pathname = req.nextUrl.pathname;
  const newUrl = new URL(`/${lang}${pathname}`, req.nextUrl);

return NextResponse.rewrite(newUrl);
