Unable to escape $ sign in subs_filter

October 10, 2017 07:06PM
Hello,

I am trying to add some code to a page which contains a $ symbol. However, I am getting the following error:

nginx: [emerg] invalid variable name

Here is a simple example of the config:

subs_filter 'example' '$';

Is there any way to escape the $ symbol? The issue occurs even with single brackets, which normally should take strings as literal without any variable substitution. It seems like a bug since this behavior should only occur with double brackets.

This issue was also discussed in the past, however, the workarounds don't work in my case
