Additional context

[ryanheise]

I am closing this issue since it does not fill in the required sections of the issue template.

@ryanheise Whats your proper format can you mention here because its to much to submit some issue.
If you think the issue is not in proper format or you can't understand your code structure better from here.

[ryanheise]

Whats your proper format

It is mentioned right in your issue above. For example:

Minimal reproduction project
Provide a link here using one of two options:

1. Fork this repository and modify the example to reproduce the bug, then provide a link here.
2. If the unmodified official example already reproduces the bug, just write "The example".

That was copied and pasted directly from the issue you submitted above. You don't need to ask me for the instructions, you just need to read them (instead of skipping over them or ignoring them) and then fill in each section appropriately.

its to much to submit some issue.

If you think submitting a bug is difficult, just think how difficult it is to fix a bug.

I will try to be fair with you and will match your commitment and attitude. If you ignore my instructions, then I will equally ignore your request. And if you don't want to put in the effort to submit a complete bug report, then I will not put in the effort to investigate your bug report. Fair?

@ryanheise Okay, man I definietly agree with you. I update the existing one but you directly closed without give any suggestions so its not right thing. Atleast some users have to face some difficulties so he/she will posted over here.

Hi @Divyanshu133

Thanks for understanding. My suggestion was that you need to fill in the required sections of your issue.

I would ask you to open a new bug report. Make sure you read the first sentence of the instructions to understand, and also read the complete instructions carefully, thanks.
