Parsing HTML extracted from RSS to post to Discord

I’m not sure how to do this.
I’v added a “Compose string” and “Text aggregator” before the “Discord” module.

but I still have 7 operation in the “Discord” output.

How ever I don’t have the warning message anymore.
Was that your suggestion @samliew ? I’m doing it right ?

Thanks in advance.

PS : I have upgraded now from the Free to Core plan, in order to avoid any limitation…
