Hi I had an interesting error here.
I used to publish the file correctly, and it worked well. But today I made little changes and published it again, it showed this error. However, it works good if I just run it on local PC and do not publish it.
I have double checked the activities folder, and project.json
Everything in the json file are in the activities folder, and mail activities are there, I didnt upgrade my uipath, only download some new packages recently, but they did not influence the mail activities at all.
I totally have no idea how to deal it, please help!
