When the SAP Gateway demo system ES5 is used in open SAP courses it frequently happens that an error occurs when calling an OData service such as GWSAMPLE_BASIC.
First of all:
Do not add Question to this or other blogs but post your question here:

Due to GDPR requlations there is no way to search for the error using your SCN user name ;-).
What would be helpful are the two values
transactionid and
timestamp.
<transactionid>B9E0A2A100BE0000E005C0DF32766BBF</transactionid>
<timestamp>20181218063818.7320590</timestamp>
This because in the error log (transaction /iwfnd/error_log) it is possible to filter for these values.
