WEB IDE Deploy issue - Build Failed

Hello

Starting yesterday I have been unable to deploy an application to a gateway server that I have been working on for a few weeks.

Everything has been fine for the last few weeks, changing code and deploying without issue.

Its a full stack web ide with a production developer account (not trial)

I now get an error message when deploying:

{"message":"dist/di.code-validation.core_issues.json does not exist or is not a file"}

Is anyone else having issue deploying?

Thanks

Andrew
