Pressing the chest while the portal's wavy teleportation graphics are happening gives the "<error> Something went wrong! (errcode 1)" message. This happens regardless of whether the player steps out of the portal cancelling the trip to the nether or if the player travels to the nether. This works the same going the other way (from Nether, tap chest as entering portal to overworld). As with other bugs that get this error message, breaking the chest after receiving this error will crash the game every time.

On my Samsung Galaxy S4 Android 5.0.1 MCPE 0.12.3, I get the error message for:

• chest
• furnace
• enchantment table
• brewing stand
• anvil

I don't get the error message for:

• crafting table
• stone cutter
  However, with the crafting table and stone cutter, the UI flashes extremely fast on the screen while going through the portal. You can repeatedly try to open these UIs and you'll see the flicker, but you'll never get the error message.

Original report:
when i have open chest and go into portal it say:
<error> Something went wrong! (errcode 1)
