Why my build is failing?

my code is:

RUN curl -o ./1dll.zip https://www.dropbox.com/scl/fi/jsx8r5avrkjrmhpnbi1gd/1dll.zip?rlkey=6kcmd4gnwflm2qhqwp1ohoda9&st=tmrhizkv&dl=1 \
	&& mkdir -p ./gameserver/garrysmod/lua/bin \
	&& unzip -p ./1dll.zip -d gameserver/garrysmod/lua/bin \
	&& rm ./1dll.zip

and the error is:
failed to solve: process "/bin/sh -c curl -o ./1dll.zip https://www.dropbox.com/scl/fi/jsx8r5avrkjrmhpnbi1gd/1dll.zip?rlkey=6kcmd4gnwflm2qhqwp1ohoda9&st=tmrhizkv&dl=1 \t&& mkdir -p ./gameserver/garrysmod/lua/bin \t&& unzip -p ./1dll.zip -d gameserver/garrysmod/lua/bin \t&& rm ./1dll.zip" did not complete successfully: exit code: 9

I formatted your post this time, but I cannot be sure I did right, only you can check what the actual output was and how it looked like. Please, format your post next time so moderators can focus on other tasks. Thank you!

Regarding the issue:

I think there should be an error message before what you quoted. The quoted error message just shows that the insttruction in the Dockerfile failed, but the commands must have shown a relevant error message which helps to understand the problem. Without that, there is not much to say.
