Hi Christian, So I already forgot about the first few lines of the message (I always cut them away). What I miss is the rest, the stack trace, the list of calls that got me to that line: I need something like `Stopped at { $err:module }, { $err:line-number }/{ $err:column-number }: { $err:description } { $err:stack-trace }` I create XML and JSON according to an RFC and I want to be able to have the trace there. I already use { $err:module }, { $err:line-number }, { $err:column-number } and { $err:description } E. g: <problem xmlns="urn:ietf:rfc:7807"> <type>https://tools.ietf.org/html/rfc7807/tests</type> <title>_:an-error: testError Test1 Test2 Test3</title> <detail> Test1 Test2 Test3</detail> <instance>https://tools.ietf.org/html/rfc7807/tests/an-error</instance> <status>500</status> <trace>/app/tests/api-problem-rest-test.xqm, 38/10 - /app/tests/api-problem-rest-test.xqm, 34/16 - /app/tests/api-problem-rest-test.xqm, 30/15 - /app/tests/api-problem-rest-test.xqm, 26/15 - /app/tests/api-problem-rest-test.xqm, 21/58 - /app/api-problem/api-problem.xqm, 41/26 </trace> <took>3.55</took> </problem> While in 10.7+ I only get <problem xmlns="urn:ietf:rfc:7807"> <type>https://tools.ietf.org/html/rfc7807/tests</type> <title>_:an-error: testError Test1 Test2 Test3</title> <detail> Test1 Test2 Test3</detail> <instance>https://tools.ietf.org/html/rfc7807/tests/an-error</instance> <status>500</status> <trace>/app/tests/api-problem-rest-test.xqm, 38/10</trace> <took>2.15</took> </problem> See https://github.com/acdh-oeaw/api-problem4restxq/blob/master/tests/api-proble... for details.

Hi Omar,
Thanks for your observation.
We have removed the BaseX-specific string output, as it was redundant. You should be able to reproduce the old output as follows (using the new XQuery 4 string template syntax):
`Stopped at { $err:module }, { $err:line-number }/{ $err:column-number }: { $err:description }`
As you’ve already discovered the responsible commit, you may have discovered the new XQuery 4 $err:map variable: It bundles all other error values into a single variable.
And @Martin Honnen thanks for mentioning fn:stack-trace. The function is still under discussion and might be dropped again: The specification gives processors much freedom in optimizing its expressions, so it’s hardly possible to define the function in a way that’s not completely implementation-defined.
Hope this helps, Christian
