EDIT: IT WAS A VISUAL BUG WHERE IT SHOWED 2 NODES, 1 OFFICIAL AND 1 COMMUNITY, AFTER UNISINTALLING AND REINSTALLING AND UPDATING THE TAB, THERE IS ONLY THE COMMUNITY NODE, BUT JUST FYI, THERE IS A VISUAL BUG AS DESCRIBED.
i have the base official cloudconvert node in my workflow, but before i knew that there is an official node for cloudconvert, i installed their community node, then when i saw that there is an official one, i naturally deleted the community one.
when i entered both the trigger and the action nodes, both didnt have a credential box to connect the api (live nor sandbox for that matter)
after searching a bit, i figured i should check the community one if it has the same issue, turns out that it actually has a credentials box; problem only exists in the official one.
clicked on the official one with the community node installed, and surely enough, it also contains the credentials box now that i installed the community one.
tried deleting the community node, box disappeared again.
