Hi!

This error typically happens when there is a problem in the ASN-1
decoding of a certificate.
You could try tracing on public_key:pkix_path_validation. If we can
get the input values
to that function we could create a way to reproduce the error and make
it much easier for us
to fix the problem.

dbg:tracer().
dbg:p(all, [call]).
dbg:tpl(public_key, pkix_path_validation, x).

Regards Ingela Erlang/OTP- team Ericsson AB
