I am creating a Sepasoft Web Service endpoint to receive ERP data. Ignition 8.1.17, WS 3.81.1 (b2022042818).
When I have a single record in the records section, there is no issue; the XML is automatically converted to a dict by Sepasoft’s module. When I add a second record, however, the call fails. I cannot even get the body to print at this point and receive this error:
do_POST TypeError: info(): 1st arg can’t be coerced to String
Any suggestions on how to work through this?
The body is arriving in a format like this:
<?xml version="1.0" encoding="UTF-8"?>
<processOrder>
<RECORDS>
<RECORD>
<ORDER>1</ORDER>
<ATTRIB1>Test 1-1</ATTRIB1>
<ATTRIB2>Test 1-2</ATTRIB2>
</RECORD>
<RECORD>
<ORDER>2</ORDER>
<ATTRIB1>Test 2-1</ATTRIB1>
<ATTRIB2>Test 2-2</ATTRIB2>
</RECORD>
</RECORDS>
</processOrder>
info(): 1st arg can’t be coerced to String
That sounds like an internal programming error in the module, not an issue with anything you’re doing. If there’s a full stacktrace, it would help prove that.

Are you calling info with a custom logger on line 573 of processProcessOrder_v1? Try wrapping your argument to info with Python’s builtin str, e.g. logger.info(str(myArg))
Yeah… not explicitly cast.
