Issue in Installing on magento 2.2.0 about magento2-custom-shipping-rate

[srenon]

@rishabhchd19 ... is this still an issue?

@rishabhchd19 ... I'm working on few other issues in 2.2. Will push an update soon

Hi, any update? :)

[rishabhchd19]

I installed version 1.3.0 and it is hiding the content of the entire page of Shipping Methods. After Disabling it, the page showing other shipping methods correctly.

Can you check your php/magento error log and let me know what the error is?

Are you doing a fresh install or upgrade from a previous version of this module?

[rishabhchd19]

The previous module was not compatible with 2.2.0 so I uninstalled and update 2.1.9 to 2.2.0 and then installed fresh using composer. Let me check the error and confirm the same. Thanks

If you are getting a white screen that means you are getting a fatal PHP error, can you check an tell me what the error is?

Since Magento change from serializing array to JSON the error may be somewhere in https://github.com/magepal/magento2-customshippingrate/blob/master/Helper/Data.php#L19

[rishabhchd19]

Yes, it'ds getting white blank screen and I am still looking for the error from the logs.

Try https://stackoverflow.com/a/34695164/1191288 (should show the error on the screen)

[rishabhchd19]

will work on it and let you confirm on the same.

Hi, I was just about to comment..but didn't get time to update here. I just tried the above method you said. I didn't get clear from the log. Yes, the problem is still there. I have found that PHP version is 7.0.24 installed and any other components that have been updated for 2.2.0 are working perfectly except this one. Right now I have created cart rules and put custom rate there for specific groups. It would be really good if worked on 2.2.0.

I just ran into the shipping methods blank screen problem. The error message that gets logged to var/log/system.log upon visiting the shipping methods configuration is

main.CRITICAL: Unable to unserialize value. [] []

@Willamin ...

1. Did you upgrade Magento recently?

2. What version of this extension are you using?

[Willamin]

Yes, I've recently upgraded Magento but that was before I installed this extension. Everything worked fine after upgrading Magento.

I'm using version 1.3.0 of this extension.
I'm using PHP 7.1.11.
I'm using Magento 2.2.1.

[Willamin]

Update: I set the config value (carriers/customshippingrate/shipping_type) manually using n98-magerun2 to what I had in development and now everything works fine. It looks like there's a default configuration set in etc/config.xml, but that didn't get saved in the database when I installed the module.
Here's what I set the config value to:

{"_1511907270182_182":{"code":"custom","title":"Shipping","price":"1000.00"}}

What can I do in my case? I was getting the same problem but using Php ver 7.0.24 and magento 2.2.1
