[Nightly] Malformed board options error.

[ScaredyCat]

Bug Report

esp32:esp32 and esp8266:esp8266 cores installed via core install but an error is generated during board list and no boards are discovered. There are currently 2 network connected esp32 boards both supporting OTA which works flawlessly from the IDE.

Expected behavior

List discoverable boards, similar to those IDE v1 port menu. Allow flashing over the network to one of those boards.

Here's the change that now prevents loading any board with "malformed custom board options":

I opened a PR on the esp8266 repo to fix this. I'll close this issue after esp8266/Arduino#8153 is merged.
Thanks for the report @ScaredyCat.

That PR has been merged, the fix will be probably released with esp8266@3.0.1.

Guess I'll close this issue when that version is released in case other people have the same issue.

esp8266@3.0.1 has been released on June 26, closing this PR.
