TypeError: Cannot read properties of undefined (reading '0')

Sorry I can't give more helpful details, just following instructions from the stack trace!

TypeError: Cannot read properties of undefined (reading '0')

{snip} nction(e,i,r){var a=i[0],n=i[1],o=i[2],s=i[3];return e[0]=r[0]*a+r[4]*n+r[8]*o+r[12]*s,e[1]=r[1]*a+r[5]*n+r[9]*o+r[13]*s,e[2]=r[2]*a+r[6]*n+ {snip}
This is most likely a bug, please report this via https://github.com/mapbox/mapbox-gl-js/issues/new?assignees=&labels=&template=Bug_report.md
and paste the contents of this message in the report.
Thank you!

The report contains only a minified TypeError stack trace, including filter-expression and WebGL-related snippets; no source file, test, or reproduction is identified. First obtain a reproducible example and the relevant unminified stack, then define the affected behavior and a regression test before changing code.
