Not able to integrate Bluez5-5.50 stack to the imx-morty-battra_r1.1 release

[dhruvkakadiya]

I used below options to build a Yocto image.

i.MX Yocto Release              : 4.9.11_1.0.0 GA
Yocto branch                    : morty
fmac version                    : "battra" (v4.14)
Target                          : imx6ull14x14evk
meta-murata-wireless Release Tag: imx-morty-battra_r1.1
VIO Signaling                   : 1.8V VIO signaling without UHS support - HW mods needed
DISTRO                          : fsl-imx-x11
Image                           : core-image-base 
Build Directory                 : build-imx6ull14x14evk

I am able to build it fine but Bluez5 stack version that I get with the image is 5.41 which is older and I want latest 5.50 stack in there so first I tried to include just PREFERRED_VERSION_bluez5 in there but that didn't help me to get that specific version automatically so then I tried adding custom dev layer along with correct Bluez5 bblayer recipes in there then getting below errors regarding parsing that recipe.

While if I use Sumo release branch for the Yocto then I am able to add the same custom dev layer fine without any issues in parsing that recipe.

So does anyone know how to fix this issue?
