Jenkins pipeline fails to deploy the code to PCF running on NGINX_buildpack "Could not validate nginx.conf: exit status 1"

I’m trying to deploy our Angular version 9 code into NGINX_buildpack which is running on Pivotal Cloud Foundry from Jenkins Pipeline. But I’m getting a strange error which is not pointing to any specific line in nginx.conf file. Below is the error that’s displaying in App Manager :

[31;1mERROR[0m Could not validate nginx.conf: exit status 1

[ERR] Failed to compile droplet: Failed to run all supply scripts: exit status 14

[OUT] Exit status 223

Any support on how to fix this issue would really help me a lot…!!
