DocBox.generate() throwsError: cannot convert the value "''" to a boolean

Pete_Lombardo · August 16, 2024, 8:54pm

This code worked a while back but now just throws an error: cannot convert the value “‘’” to a boolean. I’ve updated docbox with no change. It’s a big codebase and is actively being worked on. Any help would be appreciated.

        docbox = new DocBox( properties = { 
            projectTitle="Monolith JavaDocs", 
            outputDir="#expandPath( '../javadocs' )#"
        });

        sourcesArr = [];
        sourcesArr[1] = {dir="#expandPath( '../../core' )#", mapping="core"};
        sourcesArr[2] = {dir="#expandPath( '../../com' )#", mapping="com"};
   
        docbox.generate( source  = sourcesArr );

Is there a stack trace?

Pete_Lombardo · August 27, 2024, 2:08pm

Thanks for responding. I thought it started working but as of now it still throws this error. How can i make a stack trace?

Pete_Lombardo · August 27, 2024, 2:52pm

just an update. None of these helped:

restarted CF.
deleted output directory

Ultimately after just trying it repeatedly it still throws the error, but -at least most of - the output is generated successfully.

I should clarify that some of the files were being created before, so clearly its choking on something in my code. I just don’t know of a way to know where. Thanks!

It’s in the original error. The stack trace will tell us a lot more about what’s going on and where, because cannot convert the value “‘’” to a boolean is not a lot of info to debug with.

Can you paste the entire error into a reply here?

Pete_Lombardo · August 27, 2024, 5:11pm

sorry, i missed the catch statement at the bottom which just ouptut the message.

bdw429s · August 27, 2024, 5:21pm

Ok, so you can see the error is happening on line 597 of the class.cfm file. We look at that code and we find this: DocBox/strategy/api/resources/templates/class.cfm at development · Ortus-Solutions/DocBox · GitHub

	if(NOT param.required)

and we can tell from the surrounding code that this means one of your function arguments somehow has an empty string or perhaps two actual quotes-- not sure as the required value which is expected to be a boolean.

So, go to this line of code in the docbox strategy, wrap it in a try/catch and dump out the metadata when it errors so you can see which CFC in your code is having the issue. Then you can go track down and fix your code.
And if there’s not enough context there, the stack trace also shows us the erroring method is called from line 318 of class.cfm so you can move your try/catch up to there and dump out the arguments.metadata variable.

Pete_Lombardo · August 28, 2024, 3:25pm

So, thank you for your guidance. I did wrap the contents of the arguments.func.parameters cfloop and have stopped getting the error. oddly i can’t seem to get it to log anything though. just fyi.

have a great day and thanks for your help!

bdw429s · August 28, 2024, 3:55pm

Assuming you’re running this in a web server, just dump the metadata and abort in the catch.
