B4R version: 1.20
Parsing code. (0.00s)
Compiling code. (0.08s)
Building project (0.07s)
Compiling & deploying Ino project (WeMos D1 R2 & mini - COM8) Error
Loading configuration...
java.lang.NullPointerException

at processing.app.Base.<init>(Base.java:273)
at processing.app.Base.guardedMain(Base.java:219)
at processing.app.Base.main(Base.java:132)
