Issues generating a map from a Bedrock Realm

[cwawak]

Steps to reproduce:

1. Download backup of a Minecraft Bedrock Realm on Windows 10
2. Rename backup from .mcworld to .zip
3. Extract .zip
4. Point mcpe_viz_helper (downloaded from latest git) to the level.dat file in the .zip
5. Attempt to create map - all images, web app, any of these options give the same behavior.

Expected behavior: Creates map

Actual behavior: Web app is created, but with a blank, black map, HUGE (10GB+) log files with logs of the following errors: Parse all leveldb records NBT exception: (Invalid tag type: 0) (eof=false) (is=false) NBT exception: (Invalid tag type: 0) (eof=false) (is=false) [... and so on for ~10 gigs of logs or so ...] NBT exception: (Invalid tag type: 0) (eof=false) (is=false) Row 1600 of 1680 NBT exception: (Invalid tag type: 0) (eof=false) (is=false) NBT exception: (Invalid tag type: 0) (eof=false) (is=false) NBT exception: (Invalid tag type: 0) (eof=false) (is=false) NBT exception: (Invalid tag type: 0) (eof=false) (is=false) Do Output: nether Generate Image Generate Biome Image Generate Grass Image Generate Height Column Image Generate Height Column (grayscale) Image Generate Height Column (alpha) Image Generate Block Light Image Generate Sky Light Image Generate Slime Chunks Image Generate Shaded Relief Image Generate full-size slices Writing all images in one pass Row 0 of 16 Do Output: the-end Generate Image Generate Biome Image Generate Grass Image Generate Height Column Image Generate Height Column (grayscale) Image Generate Height Column (alpha) Image Generate Block Light Image Generate Sky Light Image Generate Slime Chunks Image Generate Shaded Relief Image Generate full-size slices Writing all images in one pass Row 0 of 16 Do Output: html viewer Copying icon images Done.

MCPE Viz completed successfully! You can launch the web app now.

I have never had any luck with the .mcworld files. for my realm I just download the realm from its setting button and then copy the contents of the newly created world to an alternate dir and let mcpe_viz work on it from there.

It would be a beautiful thing if mcpe_viz could read .mcworld files "raw" rather than unzipped, and so on. As it is, if I create the world, the map program would be happy. If I try to map one from Marketplace, I think Marketplace uses a key that thwarts mcpe_viz from working. I've not used this software lately as I've been playing Java snapshots. When we return to Bedrock I'll see how mcpe_viz is working.

Same for me, NBT exception: (Invalid tag type: 0) (eof=false) (is=false) in tens of gigs of log I have reverted to 0.0.37 with the same result, so it looks like mcpe_viz cannot handle changes from the recent Minecraft updates.

I think this may be fixed by the new versions lately. I'm going to close this. Please feel free to open a new one if it's still a problem.
