Extension error (sphinx_immaterial.nav_adapt) in synopses

[sdebionne]

when building my project, switching from the readthedocs theme (clean build directory), I get:

Extension error (sphinx_immaterial.nav_adapt):
Handler <function _html_page_context at 0x7f7e5b0dfc10> for event 'html-page-context' threw an exception (exception: 'synopses')

Running with -P:

Did you add sphinx_immaterial to your list of extensions in conf.py?

This is the error I got that I mentioned in #354 . For me the problem was that I had extension = ['sphinx_immaterial'] instead of extensions = ['sphinx_immaterial']

I can believe I made such a stupid mistake (the error message is not helping). Thank you very much!
