Cannot launch binder, from Gallery (quick URL problem) or from GH (slowly failed to launch)

Hello Pangeo devs!

From clicking “launch binder” on Gallery pages https://gallery.pangeo.io/repos/NCAR/cesm-lens-aws/notebooks/kay-et-al-2015.v3.html or https://gallery.pangeo.io/repos/NCAR/cesm-lens-aws/notebooks/EnhancedIntakeCatalogDemo.html I get this error quickly: This URL does not work: "Could not resolve ref for gh:NCAR/cesm-lens-aws/master. Double check your URL.”

The URL is: https://aws-uswest2-binder.pangeo.io/v2/gh/NCAR/cesm-lens-aws/master/?urlpath=git-pull?repo=https://github.com/NCAR/cesm-lens-aws%26amp%3Burlpath=lab/tree/notebooks/kay-et-al-2015.v3.ipynb%3Fautodecode

So, the gallery pages need updating, perhaps merely something about the URL (master vs. main), based on this googled issue: https://discourse.jupyter.org/t/cant-solve-could-not-resolve-ref-for-gh-fredericfoulonlycee-math-spe-python-master/6301

But this URL is from the launch binder button on https://github.com/NCAR/cesm-lens-aws README.md area. I might hope it would allow me to open either/both notebooks.

https://aws-uswest2-binder.pangeo.io/v2/gh/NCAR/cesm-lens-aws/binder-config?urlpath=git-pull?repo=https://github.com/NCAR/cesm-lens-aws%26amp%3Bbranch=main%26amp%3Burlpath=lab/tree/cesm-lens-aws/%3Fautodecode

It doesn't have the instant URL error, but: Loading your Binder... Your session is taking longer than usual to start! Check the log messages below to see what is happening.

Found built image, launching... Launching server... Launch attempt 1 failed, retrying… Launch attempt 2 failed, retrying… Launch attempt 3 failed, retrying…

Oh, maybe this should have gone to https://github.com/pangeo-data/pangeo-binder/issues ?
