	Functions deploy had errors with the following functions:
		ssr


	To
	try redeploying those functions, run:
		firebase deploy--only functions: ssr


	To
	continue deploying other features( such as database ), run:
		firebase deploy--except functions

	Error: Functions did not deploy properly.

	Having trouble ? Try firebase deploy--help
