How to get individual records based on record ID in a rule?

I'm trying to manually create a related action for a record type (the auto generator didn't work). I need to create an expression rule that returns an individual record based on the record ID (according to the documentation), but there doesn't seem to be any documentation on how to actually do this. I've posted what I have currently that is not working, could someone let me know what I'm doing wrong?

Thanks in advance!

Expression rule:

a!queryRecordType(
  recordType: 'recordType!{5e8d63c0-430d-4636-9dfe-e5e4c67aefc5}SH survey data',
  fields: {},
  pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: 1
  )
).data[ri!identifier]

Context field in Related Acton configuration:

{
  record: rule!SH_getSurveyRecordById(rv!identifier) /* SH survey data */
}
