Hi,
make sure you added the module 'sale' to the dependencies of your new module. Look at the manifest file of your module. There should be at least:
"depends": [
"sale",
],

FYI -it can alsao happen when there is a depends redunancy where two modules refer to each other in the manifest's depends. Only one must make reference to the other not both.

It's dependency issue, added sale dependency on your custom module
