Issues to update dataset with velo code

Hello, I would like to update my post by using velo, but when I start my code I’ve got an error Message I can not understand.

I would like to change my hashtags within a post. I made a litte program that should make this by clicking a button. Everythings works well till the update process. I get this error message “Request ID: 1615068061.33833263250173019216. Message: Not Implemented.”.
I checked the _id but it seems to be correct. Now I’m stucked.

Please can you help me to find a solution. Thank you!

Here is my code so far:

import wixData from ‘wix-data’ ;
import wixLocation from ‘wix-location’ ;
import wixWindow from ‘wix-window’ ;

$w.onReady( function () {

});

export function button1_click(event) {
searchItem()
}

async function searchItem() {

// ***** Search after Category
let category = “Karte”
let item = ( await wixData.query( ‘Blog/Categories’ ).eq( ‘label’ ,category).find()).items[ 0 ];
let res = await wixData.queryReferenced( ‘Blog/Categories’ ,item._id, ‘posts’ );

// Show unchanged itiems
console.log(res.items[ 0 ]);

// Change items - Hashtag
let queryResult = res.items[ 0 ];
queryResult.hashtags = [ “Test1”,“Test2”,“Test3” ];
// Show changed itiems
console.log(queryResult);
// Update itiems in Database
let options = {
“supressAuth” : true ,
“supressHooks” : true
};
updateHashTags(queryResult,options);
console.log( “Success” );

// Helper function

function updateHashTags (postItem,uptOptions) {
wixData.update( “Blog/Posts” , postItem, uptOptions).then( (resNew) => {
let items = resNew; //see item below
const alertSuc = $w( ‘#succMsg’ ).show();
//console.log(items);
})
. catch ( (err) => {
let errorMsg = err;
const alert = $w( ‘#errMsg’ ).show();
//$w(‘#errTxt’).show();
console.log(errorMsg);
});
}

}

Best regards
Ulrich

Note that the permissions for Blog/Posts collection is read-only.

Hi Yisrael,
is there any possibility to make changes of this content by velo? Do I have to make my own collection? And if yes, how do i get access to all the posts are made already? I guess, that I have something not understand in principle, have I?
Thank you in advance!

The Wix Blog does not currently have an API available for interfacing with Velo. This feature is planned, but there is no ETA.
