When i try to build the image using docker build from my local repo then i am getting this error. It appears that the script file contains additional characters such as \r (carriage return) and \t (tab) at the end of each line. These characters are not visible when viewing the script in a text editor, but they are interpreted as part of the script when it is executed, causing syntax errors. I used sed to display each line of the file with non-printable characters represented as \r, \n, etc.

I replaced this part of the Makefile with the following:

frontend: ## Build frontend
	$(call frontend_env)
	cd $(OPENAPI) && yarn build
	yarn install
	@-rm -rf $(BUNDLE)
	@-mkdir $(BUNDLE)

	tr -d '\r\t' < ./scripts/tests.sh > temp && mv temp ./scripts/tests.sh
	@bash ./scripts/librejs.sh
	@bash ./scripts/cachebust.sh

And there are no errors while building this part.
