@lock9, can this transaction be one of yours? I'm interested in how this manifest was produced, fixing the node side is rather trivial, but I don't see how this can happen in a regular compiler use flow.

Hello @roman-khimov,
Yes, that's mine. Maybe it's my serialization / deserialization code that has caused this?
Note: Maybe it's unrelated (probably is), but I saw this error neo-project/neo#3439 when I tried to send a transaction using an incorrect network magic.
Nef serialization code:

It's all about the manifest. Compiler outputs valid manifest on its own (with all fields), but if you do some additional processing then empty values can get mangled.

Hm. Could that be caused by mismatching NEF/manifest? Is the manifest generated when there are compilation errors? I saw some weird behavior when I tried to recompile and redeploy a contract with syntax errors.
Could concurrency cause that? I also recompile my files frequently (automatically)
Maybe I formated the manifest json (added indentation) before deploying it (I can't recall it)

Maybe I formated the manifest json (added indentation) before deploying it (I can't recall it)
It's not indented, but it looks like it was edited somehow. Compiler always emits groups/trusts/features fields, but they're missing from the manifest.

I didn't make those changes manually. I remember being confused about the permissions, but I'm sure I didn't change the manifest.
