Customer has run a legacy API call to OO 10.6 it failed with "The request sent by the client was syntactically incorrect"
The API call was:
This problem not always happen, just happen sometimes.
I searched the resource and got the problem of "The request sent by the client was syntactically incorrect" is typically caused by the data for the form is inconsistent with parameters that method needs. And from customer's log I saw many times the OO is reconnect to DB.
So I suspect there may have some data are not synchronous in database.
However the customer hope we provide specific reason to prove this issue. While I did not find any special information about this in log file.
Does anyone knows how to debut this problem, or give me some clue.
I attached related files.
