Cannot read property 'getUTCFullYear' of null, pages with calendars are not loading

nepatriot · November 12, 2020, 5:44pm

Wappler Version : 3.5.2
Operating System : Windows 10
Setup: PHP, Docker Local

Expected behavior

What do you think should happen?

My application that contains calendars on it should load correctly instead of a showing a blank page.

Actual behavior

What actually happens?

When trying to load a page with a calendar on it I get the following console error:

main.min.js:formatted:3138 Uncaught TypeError: Cannot read property 'getUTCFullYear' of null
    at e.getMarkerYear (main.min.js:formatted:3138)
    at e.startOfWeek (main.min.js:formatted:3342)
    at e.startOf (main.min.js:formatted:3324)
    at d (main.min.js:formatted:3643)
    at e.buildRangeFromDuration (main.min.js:formatted:3653)
    at e.buildCurrentRangeInfo (main.min.js:formatted:3610)
    at e.build (main.min.js:formatted:3576)
    at main.min.js:formatted:3759
    at er (main.min.js:formatted:3765)
    at e.reduce (main.min.js:formatted:4666)

The page does not load and is just blank.

How to reproduce

Starting with a blank page, create a title and add a calendar to the page:

Load the page in Google Chrome and you see this:

Remove the calendar from the page:

My application was working in the prior version so I’m fairly confident this has to do with the new version.

Is there a way to roll back to the prior version until this is fixed?

Looks like the latest App Connect build was not bundled with the Wappler update. Here the correct file:

dmxAppConnect.zip (22.2 KB)

@patrick, thank you for your help.

I renamed the original dmxAppConnect.js and replaced it with the version above.

Redeployed. Emptied cache with a hard reload and am getting the same error.

Do you have a link where I can check it?

nepatriot · November 12, 2020, 9:37pm

Unfortunately, the app is currently local.

I can share the GitHub repo with you if that’s helpful.

patrick · November 12, 2020, 10:11pm

I got exactly the same error in my testing and it should be solved with the updated file.

nepatriot · November 12, 2020, 10:29pm

Weird. I replaced the file as you said to. Do I need to restart Wappler or Docker Desktop? Maybe reinstall Wappler?

patrick · November 12, 2020, 10:32pm

Wappler has the wrong file, so reinstalling Wappler won’t help. Replace the file in the dmxAppConnect folder of your project.

nepatriot · November 12, 2020, 10:42pm

That’s what I’m doing.

Here is the file in the folder:

File deleted:

File extracted from Download folder into \dmxAppConnect:

Page doesn’t load. Am I missing something?

When I open the file in Wappler, I see the file version is 1.9.20 @build 2020-11-11 18:43:12

Not sure if this is helpful, but when I hover over the error, it’s pointing to the fullcalendar plugin:

I have exactly the same issue with the new release (Mac OS Catalina). Replacing dmxAppConnect.js doesn’t help.

Fixed in Wappler 3.5.3

nepatriot · November 13, 2020, 3:32pm

Thank you @patrick and @Teodor.

Unfortunately, after updating, it looks like I’m getting the same error.

stormvision · November 13, 2020, 3:39pm

Thanks. Works for me now.

nepatriot · November 13, 2020, 3:45pm

@stormvision, can you confirm all you did was just update the application and it worked? Did you do anything else?

stormvision · November 13, 2020, 3:55pm

Hi @nepatriot,
I had to do the following steps:

Delete my modified (the old) dmxCalendar.js
Save my index.html to let Wappler automatically create the new dmxCalendar.js
Reload Design View of my index.html

Then the calendar worked again.
After I replaced the new dmxCalendar.js with my old (modified) one it worked also fine again.
