Try replacing single quotes (') to double quotes (") and double quotes(") to backslash double quotes ("). Some terminals may not process single quotes correctly.

aws dynamodb update-item \
--table-name test \
--key "{\"testid\": {\"S\": \"testing\"}}" \
--update-expression "SET userType = :ut" \
--expression-attribute-values  "{\":ut\":{\"L\":[{\"S\":\"PRIMARY\"},{\"S\":\"SECONDRY\"}]}}" \
--return-values ALL_NEW
