In the screenshot I shared, I was in “Resolve” mode where I can Run Once and the flow restarts from that point.
Sometime the issue gets solved after just one try and sometime it take 20-30 minutes of waiting to bypass the error.
I spoke with the support and they said that Wordpress is returning an HTML code message instead of JSON. Other people faced that too for sure.
If you are able to escalate this matter, it would be helpful to improve the products.
Still getting that error randomly on different modules (create post, media ID, upload media). I got a reply from support team that WordPress is returning an HTML response instead of JSON.
I don’t know if there is a solution for now.
