Hi 

We are hiring employees for UK legal entity and we are hitting the following error. I did go through the error and did the following task

Add a registration row, registering your Legal Reporting Unit with ‘United Kingdom HMRC’.

Even after this we are getting the same error.

We are able to hire an employee for the same legal employer by not selecting the Tax Reporting Unit.

this is the error stack from the worklist
