Hello,
On a working Odoo system, creating an invoice result (after some long time) with an invoice without any template applied to it. (see image in attachement)


We think that it is linked with viewing but not editing/saving settings in general settings => invoice template (in french: Paramètres généraux=> Modèle de document)


We see the following log line when generating the invoice:
2019-03-11 09:21:02,439 1 INFO datapartner odoo.addons.base.ir.ir_actions_report: The PDF report has been generated for records [23].


Also while saving the invoice template we see the following log line:
2019-03-11 09:20:40,474 1 WARNING datapartner odoo.models: res.company.write() with unknown fields: active_id, active_ids, active_model, lang, module, params, search_disable_custom_filters, tz, uid
2019-03-11 09:20:40,474 1 INFO datapartner odoo.modules.registry: At least one model cache has been invalidated, signaling through the database.


Could anybody help in this? We were able to reproduce the problem on two different systems using odoo 11 and 12 (both system used docker images).


Best regards and thanks in advance,
