can you provide code to reproduce the bug? nim compiler version as well.
I managed to narrow down the issue. It seems that any DateTime field in an object causes the error. I've attached a test case. I understand this isn't something that's handled by MsgPack spec. However the error message is misleading. Is there anyway to fail with a more appropriate error message when a type that isn't compatible is in an object?
msgpack4nim depends heavily on Nim generics, much of the serialization code generated by the compiler, and that come with a cost. one of them is misleading error message.
a better serialization framework would be using macros + generics to generate better error message.
btw, your problem can be solved by overriding pack_type
and unpack_type
for DateTime
.
When I try to unpack an object type that contains int64 types I get:
The object I'm packing/unpacking is a seq of an object type. This is to and from a FileStream.
