After an update of the Dynamic Portal we noticed a few liquid error’s on our portal.
Upon investigation we found that the rendering of an empty content snippet is the root cause of this error. We had contacted Microsoft and they have confirmed that this is product bug and will be fixed in future releases.
In the meantime, here are a few workarounds that can be applied to your portal:
Logic apps by default have data retention of 90 days. The cost of Data retention can grow exponentially if not managed properly. Unless needed for business requirements to keep the run history of your logic apps I would suggest the settings of Data retention to 7 days the lowest setting available. As of March 13th 2019 the data retention setting can only be configured from Azure after you have enabled and/or deployed the logic apps.
We ran into a problem after updating to Microsoft Portal 18.104.22.168 and had to do some digging around to find the root cause. We captured our learnings and are sharing them here for anyone who runs into a similar issue.
