Unable to accept repeteable quests without restart the game

When I go to a trader to accept a repeteable quest, the server log give the error TypeError: Cannot read property 'trim' of undefined and didn't do nothing, but after that I can't give object missions to traders. If I restart the whole game, including server and launcher, after start again, the mission is accepted. If I replace it the error appear again

Does this happen with all repeatable quests? or just some?

What steps do i need to perform to get the error.

All repeteable quests

Be lv5

and I got that error

Right now I have this missions completed:
