Hello
I write to you because I saw that you had a problem with o.s.SpringApplication some time ago and you managed to solve it ( DeemOpen/excord#11 ), the project in which I work presented a similar problem and I wanted to know how you managed to solve it, to know if you could help me with my problem.
