Error with mikado serialise: 'Engine' object has no attribute 'cursor'

[bbista]

Hello,
I am having trouble with the mikado serialize step. I get this error every time:

mikado serialise --json-conf configuration.yaml --xml mikado_prepared.blast.tsv --orfs mikado.orfs.gff3 --junctions portcullis_filtered.pass.junctions.bed -bt /uniprot/TSEprotein.faa

Mikado crashed, cause:
'Engine' object has no attribute 'cursor'
Traceback (most recent call last):

The log file for serialize looks like this:

I am using Mikado v2.3.4 installed using the following steps:

mamba env create -f environment.yml

pip wheel -w dist .
pip install dist/*whl

I only have issues with the serialise part.

Any help is greatly appreaciated.

Best,
bbista
