Bitbake do image failure - yocto

Question

I have been successfully building an image for many days now. I add all of my custom files to GitLab. I have not knowingly made changes to my build environment. I am now getting errors can can not build my image. Can anyone understand what this error is telling me? I have tried looking it up but nothing seems to work.

If you get an error similar to this delete your build folder. Then recreate it. For NXP devices they give you the command
DISTRO=fsl-imx-fb MACHINE=imx6ull14x14evk source imx-setup-release.sh -b build-fb
Save your local.conf and bblayers.bb file to git or to a new location.
Delete the build-fb folder and re-run the command above. Pull in any changes from git or files saved elsewhere.
Re-run bitbake. This got my workspace back. Because you are not deleting any of the downloads folders the build takes little time. All the time is spent compiling sources.
