error: internal verification failure, sorry! {PrepAndWrite() called on non-diskcacheable stuff}

[#1]

I am getting this error whenever I export one particular comp out of 4 total. Here's the thing- these comps are self-made templates, as in I've duplicated one comp three additional times and made changes. They still export with no apparent issues, but this error pops up after the queue has been completed.

The issue sounds related to the file and folder permission of Mac OS. Please check the permission of everyone.

I'm having the same issue. All my permissions seem fine. I'm able to eventually finish rendering the compositions, and whatever is going wrong seems to recover. 

For example, I set up a queue to render last night:
I had 9 compositions, using 2 different templates with master properties set from imported .csv files.

Template 1: Both renders completed, but the log for each has multiple instances (well over fifty each) of this error, before completing, with no other errors.  Rendered files appear to be ok.

Template 2: The first copy renders, and the log also has this error, but only 18 copies of the error message. The remaining instances render without error, but averaged 40 minutes each to render. All compositions finished rendering, and appear to be ok.

For a check, I re-rendered one of the Template 1 compositions and this time got "only" 30 logged copies of the error, and the composition completed.

The exact text of the error is:

After Effects error: internal verification failure, sorry! {PrepAndWrite() called on non-diskcacheable stuff}
