We advise using standard scrum projects. Here is a quick instruction which project type to select.
If you are seeing similar warnings it would usually mean that you need to add missing custom fields to your project screens.
Identify your missing fields
First of all you need to identify what the numbers of your custom fields stand for i.e. find the name of the numbered customfields used by the plugin. These fields obviously have different numbers for different instances so you have to pay attention to your 'Program warnings' screen which gives you the 'Project key' and the 'customfield_number' you need to look after.
Now go to Settings >> Add-ons >> BigPcture/BigGantt Task configuration menu on the left and find the fields.
You might want to use CTRL+F to find it. Note also that it may be necessary to expand the drop down options to find the right customfield and if your program is using per project configuration please remember to check the correct Task configuration customfields.
Add the missing fields to your project
Once you know what your fields are, you have to add these fields to the screens of your project.
Go to your projects in Jira and choose the project identified by the KEY you see in the error prompt.
Choose any issue, open it in new browser tab.
From the 'Admin' dropdown menu choose 'Where is my field?'
Start typing in the name of the field which you identified is related to your error and choose it from loaded options.
Once you get the dialog box , scroll down the prompt and click the "Scrum Default Issue Screen" link next to red [X] icon (or another screen which is the proper screen to configure for your particular configuration).
It will take you to the "Issues Configuration screen".
Here you need to add the name of the field which you identified is related to your error at the bottom 'Select Field' input.
Be sure to add all your missing fields.
Clear the error log
The final step is to click 'Clear log' button as soon as the pop-up error message appears again.
That's it but if you still need more information you can find detailed documentation in this article.
