Unable to start meetings with pre-uploaded presentations

[thegcat]

Starting any meeting with a pre-uploaded presentation leads to the following error:

Error: The createTime parameter submitted mismatches with the current meeting.

The createTime query parameter in the URL seems to be the time of the last session of that room instead of the current time/the time of the meeting that should be created. This happens with any attachment type and size we tried, from 200kB to several MB, PDF, images, …

As a last note this happens to rooms that already worked some time ago, with a pre-uploaded presentation that also existed already at that time. This also happens to other rooms with a newly uploaded presentation.

I'm not quite sure how I would go to debug this, I haven't found any errors that seemed relevant in the Greenlight or Scalelite logs.

Versions:

• Greenlight release-3.4.1
• Scalelite latest docker v1 release (df6c00f198bd)
• BBB 2.7.15 (786)
