When using curl to communicate with motion, all the params must be
URL-encoded as required by HTTP protocol. Percent symbols is a special one
that is used to encode hex values. In order to use percent symbol as is it
is required to encode it as double percent: %%, or as a hex value (like you
are using) %25
However, the percent symbol is also a reserved special symbol in motion. So
after the URL conversion you will end up having a string with a trailing
percent sign. Which confuses motion as it expects a specifier to follow.
