Please help me to solve the issue, Thanks
As per the Cakephp github issues:
PHP 7.2 has changed count's behavior
that's why you are getting errors.
PHP 7.2 has changed count's behavior causing problems with QueryCompiler
You can follow the below link or change your PHP version to 7.1 or less to resolve this issue.
Stop warnings when using count in QueryCompiler in PHP 7.2
it looks like you are passing some wrong data to count function, guess you are passing some query directly to count. Or something like that.
If you may show the code of the controller you are facing issue it may be a great help.
there is solution for you....

please check your php version...
I've got a Domain Driven Design solution and for some reason, I'm getting this exception at RunTime when the API call is made through GateWay:
One or more errors occurred. (Method not found: 'Void FluentValidation.AbstractValidator`1.When(System.Func`2<!0,Boolean>, System.Action)'.)
The error occurs as below:
I have solution like this:
The main 4 project I'm focusing on right now are:
Core.Model
Account.Api
Service.Api.Gateway
Web.ClientSite
Web.ClientSite makes request to Service.Api.Gateway which then calls Account.Api.
Note that Core.Model is referenced everywhere
VERY IMPORTANT: If I remove the reference of FluentValidation from Core.Model, the exception disappears.
I'm hoping these information is enough. Why do you think I'm getting this exception and how can I eliminate.
Looks like some of libs (ocelot) are incompatible with new changes in FluentValidation 8.1.2. Try to downgrade to FluentValidation before 8.1.2. Hope it helps
I got similar exception:
System.MissingMethodException : Method not found:
'FluentValidation.AssemblyScanner
FluentValidation.AssemblyScanner.FindValidatorsInAssembly(System.Reflection.Assembly)'
In my case I needed to upgrade the ediatR.Extensions.Microsoft.DependencyInjection and MediatR.Extensions.FluentValidation.AspNetCore packages as well to fix the issue.
I'm new to polymer and I started to follow this easy first tutorial on the official website
http://www.polymer-project.org/docs/start/tutorial/step-1.html
all was very easy but nothing was working. Or better, I have only one problem. When I tap on the top menu ("All or favourite") nothing changes and I get this error on console
Uncaught TypeError: undefined is not a function Element.js:104
Selected: favorites (index):65
Uncaught TypeError: undefined is not a function Element.js:104

I thought I did something wrong so I downloaded the example file but I have downloaded the source of the example and I still get the same errors.
Any help? =)
Thx everyone!
Some components in the tutorial repo were out of sync. If you pull the updated repo, these errors should go away.
Updating chrome to version 35 or use Chrome Beta
It errors on my linux box which has Chrome Version 34.0.1847.137.
It works on windows7 with Chrome 35.0.1916.153m
I had the same problem.This is the error report https://github.com/Polymer/polymer-tutorial/issues/3
And this is where you can find the answer

It worked for me :)
I'm currently develop an Objective-C library that links to the MariaDB C connector. I believe there is a problem with the library, though.
Every time I execute my code I get very strange errors on the console. The -(id)init method of my library calls mysql_init(NULL) to initialise the library but as soon as I return from -(id)init I get the following errors in the console:
Object 0x10643df70 of class XXX autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
Thing is, there is no multithreaded code being executed and if I run the same - (id)init without the call to mysql_init(NULL) the errors disappear. I believe the libmariadb library is causing these errors to appear. I don't get why though.
Do I need to build it with any special command line switches? Am I calling the right methods? I obviously used the MySQL online documentation as a guide.
Make sure you add this anytime you have a new thread:
#autoreleasepool {
//enter code here
}
Have you tried latest revision from launchpad?
Also try to build libmariadb with -DUNDEF_THREADS_HACK and
CMAKE_USE_PTHREADS:BOOL=OFF)
I was busy with other stuff for a while. I've since updated MariaDB to the latest version and, as far as I can tell, it works fine.
I'm desperately trying to send a message as JSON to a PHP script.
destination d_php {
program("/usr/bin/php -f /data/htdocs/log.php" template("$(format-json)\n") ) ;
};
The php script is fine. Using simple macros works well, but the "format-json" function does always return this:
error in template: $(format-json)
I tried everything I could find in the documentation, but all response I get is "error in template". The official docs (link) even use 2 different spellings, not very promising.
Any ideas?
the format-json and format_json syntax should both work, hyphens and underscores are equivalent in syslog-ng.
As for the actual problem, have you tried setting the scope parameter of format-json, like "$(format_json --scope selected_macros)"? By default, it is empty, which means there is nothing to format.
HTH,

Found the reason. Apparently, syslog-ng is split into separate packages on Ubuntu (12). I had to install syslog-ng-mod-json.
It's really a shame that syslog-ng doesn't give the slightest hint that the function is missing or unknown, instead of some general error.
If you are compiling from the source, you shall install json-c library first (yum install json-c-devel).
