When processing orders you might come across the "Fault – UnrecoverableClientError (…) Invalid content was found starting with Element StreetLines (...)" error.
This message is shown when part of the address, specifically the street lines is filled up with invalid values.
For example, when a person or company name is entered in these fields or any other element that makes the address incorrect is filled up there, FedEx cannot validate the address.
Feel free to follow the step-by-step guide written below or the video guide, as you prefer:
To do so:
1. Find the order through any of the possible ways (after Import Orders, Batches, Order History, etc) as it applies to the case
2. Click the edit button of the order you wish to change
3. Make the necessary changes in the order (example)
4. Press Save to apply the changes
If the rest of the order's information is correct, you will be able to process it.
