Describe the bug
I noticed today that the bridge I am working on has an empty id field in feed articles, even though I do provide a relevant value to $item['uid'] in the code.
Turns out the value I am providing is an integer and RSS-Bridge does not like that. After converting to string with strval, it works as expected.
Seems to me that this is a bug? And if it is not, then I suppose it should be documented, as I did not see anything on this in dev docs — unless I missed something?
