Code 500 (Internal Server Error) - Data not saved on Appwrite DB

Hi Guys, Could someone please help with the below issue? I am keeping getting the following error, while creating a post and trying to save it on my Appwrite DB. User auth and creation works perfect, user is saved on the DB:

"api.ts:117

   POST https://cloud.appwrite.io/v1/databases/65955c1f63e8af139596/collections/65955c743b49830747b8/documents 500 (Internal Server Error)

Error creating post document: AppwriteException: Server Error at Client.<anonymous> (http://localhost:5173/node_modules/.vite/deps/appwrite.js?v=34b59556:850:17) at Generator.next (<anonymous>) at fulfilled (http://localhost:5173/node_modules/.vite/deps/appwrite.js?v=34b59556:488:24)"

my console.log (client side) is showing that the post has been created but is not getting saved to the DB.

Here are my code snippets - React+Vite:

1 - from PostForm.tsx

type PostFormProps = { post?: Models.Document; }

const PostForm = ({ post }: PostFormProps) => {

const { mutateAsync: createPost, isPending: isLoadingCreate } = useCreatePost();
const { user } = useUserContext();
const { toast } = useToast();
const navigate = useNavigate();

// 1. Define your form.

const form = useForm<z.infer<typeof PostValidation>>({ resolver: zodResolver(PostValidation), defaultValues: { caption: post ? post?.caption : "", file: [], location: post ? post?.location : "", tags: post ? post.tags.join(",") : "", }, })

// 2. Define a submit handler. async function onSubmit(value: z.infer<typeof PostValidation>) { // Do something with the form values. // ✅ This will be type-safe and validated. const newPost = await createPost({ ...value, userId: user.id, })

if(!newPost) {
    toast({
        title: 'Please try again'
    })
}
navigate('/')

console.log(value)

2 - From queriesAndMutations.ts:

export const useCreatePost = () => { const queryClient = useQueryClient(); return useMutation({ mutationFn: (post: INewPost) => createPost(post), onSuccess: () => { queryClient.invalidateQueries({ queryKey: [QUERY_KEYS.GET_RECENT_POSTS], }); }, }); };

3 - from api.ts:

export async function createPost(post: INewPost) { try { // Upload file to appwrite storage const uploadedFile = await uploadFile(post.file[0]);

  if (!uploadedFile) throw Error;

  // Get file url
  const fileUrl = getFilePreview(uploadedFile.$id);

  if (!fileUrl) {
    await deleteFile(uploadedFile.$id);
    throw Error;
  }
  // Convert tags into array
  const tags = post.tags?.replace(/ /g, "").split(",") || [];

   // Save the post in DB
   const newPost = await databases.createDocument(
    appwriteConfig.databaseId,
    appwriteConfig.postCollectionId,
    ID.unique(),
    {
      creator: post.userId,
    //   likes: likes,
      caption: post.caption,
      imageUrl: fileUrl,
      imageId: uploadedFile.$id,
      location: post.location,
      tags: tags,
    }
  );

  if (!newPost) {
    await deleteFile(uploadedFile.$id);
    // throw Error;
    throw new Error("Failed to create post document.");
  }

  return newPost;


} catch (error) {
    console.error("Error creating post document:", error);
  }

}

// ============================== UPLOAD FILE export async function uploadFile(file: File) { try { const uploadedFile = await storage.createFile( appwriteConfig.storageId, ID.unique(), file );

  return uploadedFile;
} catch (error) {
  console.log(error);
}

}

// ============================== GET FILE URL export function getFilePreview(fileId: string) { try { const fileUrl = storage.getFilePreview( appwriteConfig.storageId, fileId, 2000, 2000, "top", 100, );

  if (!fileUrl) throw Error;

  return fileUrl;
} catch (error) {
  console.log(error);
}

}

// ============================== DELETE FILE export async function deleteFile(fileId: string) { try { await storage.deleteFile(appwriteConfig.storageId, fileId);

  return { status: "ok" };
} catch (error) {
  console.log(error);
}

}

Sorry for the multiple messages, but I wanted to provide the different parts of the code
