Description
When you are performing “read by guid” testing in OData request, you meet with the error message Malformed URI literal syntax .

Keywords
Postman, OData test, read by guid, Malformed URI literal syntax, regular_expression
Root cause
For example, the url used:
https://ldciag3.wdf.jerry:44354/sap/opu/odata/sap/Z_C_ORDER_VIEW_CDS/Z_C_Order_View(order_guid=guid’00163EA7-2000-1ED2-85EF-EFADF195A1B2’)
Note: you must add the prefix ‘guid’ before the guid value as naming convention.
Debug where this error message is raised, and we reach the framework code in line 22, where the validation is done based on the hard coded regular expression.
Solution
The solution for line 22 is clear, change the guid in url into “00163EA7-2000-1ED2-85EF-EFADF195A1B2”, and the validation will pass.
