project automation search for a custom field which contains reserved JQL character

[S N]

I used JQL to link issues that custom field A equals another issues' summary. 

My JQL is summary ~ {{issue.custom field A}}, it works if summary doesn't contain "+" or "/", and resulted in error if it does have. 

Error in the JQL Query: The character '+' is a reserved JQL character. You must enclose it in a string or use the escape '\u002b' instead. 

I tried to revise to summary ~ \"{{issue.Related Contract}}\", but doesn't work either.

Hi @S N 

You were on the right path. Just ditch the escape character and simply write:

summary ~ "{{issue.Related Contract}}"
