I am trying to write standalone Bokeh utilities with interactive CustomJS elements that can be saved as HTML files for later use. In previous versions of Safari (14.x.x, Early 15.0), examples like the one given below opened just fine and worked as expected. Safari 15.1 (17612.3.5) yields an NSPOSIXErrorDomain:1 error. Current versions of Chrome and Edge (as of writing this post) open the file just fine.
Even running the example below in Jupyter in Safari with output_notebook works as expected (and can also be run in a separate window by omitting output_notebook), but trying to open the generated file produces the error.
I’m sure this is a Safari issue, and not a Bokeh one, but I’m wondering if anyone has any ideas.
