Troubleshooting
Problem
When using the IBM Food Trust Trace API, a customer may find that payloads cannot be retrieved.
Cause
If payloads are submitted with the form of:
<epcList>
<epc>urn:ibm:ift:product:class:7891103000010.7891103186196</epc>
</epcList>
<epc>urn:ibm:ift:product:class:7891103000010.7891103186196</epc>
</epcList>
Since the epcList and epc element were used in the xml, this store the data provided as a epcID in the payload. We can see this when we view the payload:
"epc_ids": [
"urn:ibm:ift:product:class:7891103000010.7891103186196"
],
"urn:ibm:ift:product:class:7891103000010.7891103186196"
],
So, if it is desired to retrieve this data based on the epc, one would have to use the trace query on the epcID. If, however, it's desired to have the payload returned via a product trace call through the API then the productList and product element would have to be used in the payload.xml as seen below:
<productList>
<product>urn:ibm:ift:product:class:7891103000010.7891103186196</product>
</productList>
<product>urn:ibm:ift:product:class:7891103000010.7891103186196</product>
</productList>
We are in the process of updating the annotated payload.xml and the other payload documentation to include this information.
