Oh, didn’t come to think of it and made no copies of the console message, sorry. Does the console keep a history somewhere?
The problem was a .mhtml-file. I tried to replicate the problem in unsynced Joplin on my backup laptop. But strange enough, exported with flying colours. Then updated Joplin to .167, kept the .mhtml as a resource, and exported successfully.
Finally, attached this very same .mhtml again on my first laptop. Exported without console nagging about anything.
