Well, it's October 2024 and I am still getting this issue. In lieu of creating another topic post I thought I would just shout into the void in my frustration.
Trying to set a tiny area (like, 5mb) for offline. After a few months of working with FM I know the pitfalls that ESRI have unintentionally (I presume) placed in the way.
- as others have said, you gotta have feature layers. More than this, you must have layers with GlobalIDs, but then attribute types with 64 bit seem to stop the creation of GlobalIDs. I work with shapefiles and geopackages generated by myself or provided. If I am getting data ready for FM I just run everything through 'Features to Geodatabase' process and that seems to spit out something FM likes
- everything must have sync ticked, which I guess is obvious
- if you are using background imagery you cannot just use any background imagery - how dare you. I stick with 'World Imagery - for export'
Yet, despite all this, and burning offerings of 1:25,000 topo maps to the capricious ESRI god, I still have times when the offline area will not generate. No explanation, just the message 'Failed'. This does not engender a love of ESRI, particularly considering the rather large amount of money that my organisation burns to satiate this uncaring deity. Like many of you, I am doing this for work and during work hours, so my time to **bleep** about trying to work out what went wrong - when it worked yesterday perfectly fine - is exceptionally limited. It does lead to feelings of frustration, but it seems to happen quite a lot with ESRI, so that frustration generally subsides into a resigned acceptance that sometimes - despite all the gloss and hoo-ha - ESRI create stuff that is just a little bit ordinary.
