OSError: libgomp.so.1: cannot open shared object file: No such file or directory

I'm deploying the open-source https://github.com/MincYu/gillis-open-source model on my aws lambda using aws sam-cli. This whole application consist of multiple functions, a master function and multiple worker functions. After deploying it on aws lambda getting this error when I'm trying to invoke the master function. Badly waiting for a solution for the following error.
