If the employment restrictions says 'no', that's ok to have employer and/or noc values.
Check this manual from CIC webpage:
https://www.canada.ca/en/immigratio...nt-applicants/bridging-open-work-permits.html --> Look for 'Determining if nomination has employment restrictions', there you gonna have this:
Provinces and territories may include an employer or the name of the occupation and the National Occupational Classification (NOC) code and still indicate that there are no employment restrictions. In these cases, the applicants are eligible for an open work permit, provided they meet the other eligibility criteria. A separate letter from the applicant or the nominating province to confirm that no employment restrictions exist should not be requested.
I also indicate to read all the manual as it will have all the requirements, and how the officer is supposed to evaluate your application.
