Besides, the API is configured to port 8000.

After some testing I found that the problem was the name of the environment variables in the Spring application's yaml file. The most strange was the error about "MongoDB" where i not used it!!!!!!

The solution was change de variables names.

Be careful the name variables. When similary the environments, can do strange errors
