Error removing/deactivating account

[vmario89]

Hi, i am running Matrix Synapse and everything seems to be working fine except deleting once created users. I am getting the following error.

I am running the following version on Ubuntu 16 system:
ii matrix-synapse 0.34.0.1-0matrix2 all transitional package
ii matrix-synapse-py3 0.99.1.1+xenial1 amd64 Open federated Instant Messaging and VoIP server

The endpoint https://matrix.domain.tld/_matrix/identity/api/v1/ is available and returns an empty object as described in https://matrix.org/docs/spec/identity_service/latest.html#get-matrix-identity-api-v1

I am running mxisd Service to deal with own identity. But i had the problem described here before that already (using vector.im / matrix.org)

Anyone an idea on how to work around this? Regards and thanks, Mario

one addition: Error looks the same in UI like in this issue: element-hq/element-web#7717
