3 years ago Well, this is another undocumented edge case of postgres encoding (similar to edgedb/edgedb#2266)
Here is what we get. Descriptors:
Output Descr [
BaseScalar(
BaseScalarTypeDescriptor {
id: 00000000-0000-0000-0000-000000000101,
},
),
BaseScalar(
BaseScalarTypeDescriptor {
id: 00000000-0000-0000-0000-000000000100,
},
),

b"\x81g\xb4\xb8" // number of elements in the object !?!?!?
b"\x8e.\x11\xeb\x9c\xb4\x8b~\x81$\x18\r"This is also reproduced in python:
RuntimeError: cannot decode Object: expected 1 elements, got 2171057336And JavaScript:

Steps to Reproduce:
Objectruns into a different bug)I don't know how to trigger this bug without
minormax, but soon we will likely forbid passing objects (or object arrays) to either one of these. However, there might be other ways to trigger this that I just haven't come across yet.
