Internal Server Error when trying to query oobi for delegated multisig AID

[lenkan]

Currently, we are experiencing internal server errors in KERIA for a multisig AID that has been delegated from another multisig AID created in keripy. The error we are experiencing is this:

2024-04-17 12:36:22 [FALCON] [ERROR] GET /oobi/<multisig-prefix>/agent/<agent-prefix> => Traceback (most recent call last):

msg = bytearray(serder.raw)  # make copy into new bytearray so can be deleted
AttributeError: 'NoneType' object has no attribute 'raw'

The impliciation of this is that no one can resolve the OOBI of our multisig AID.

We have not been able to create a consistent reproduction. There is a related issue in keripy for witnesses: WebOfTrust/keripy#762.

Does anyone have any idea of what could be causing this?

We are using keria version: 0.1.2

From our KERI dev meeting:
Related to the fix from @rodolfomiranda which was pushed into KERIpy WebOfTrust/keripy#746. The current instance is probably no good, but in the future this issue shouldn't occur. If you receive an additional signature the escrow was causing it to be deleted.
It was merged to main but isn't available in a release. A dev release can be created on request.

Based on discussion with @lenkan it would be helpful to have a test environment as well as container image that can setup GLEIF external AID to allow QVIs to practice their multisig setup, etc.
