Some widgets are not refreshing with proper content

[basia-wulnikowska]

Description

We found out that there is a problem with refreshing data on some widgets. Currently we know about Jira Buckets and Zabbix - CPU utlization metric. A cause on backend side may be similar, so we decided to put these problems together in this one ticket. Detailed steps to reproduce are defined below.

To Reproduce - Jira Buckets

1. Go to mnt folder on you local repo and copy config files (.json) to some folder
2. Delete config files
3. Build with ./gradlew and observe tasks:
   3.1. When undeplyLocal will end, delete non-hidden files from content folder (widgets)
4. When build will end:
   4.1. Copy your configuration files from step 1 into mnt folder and accept replacing
   4.2. Build with ./gradlew once again

b) Create new project (remove config before to get sample config)

• navigate to jira buckets widget (You will see that widget have no data)
• click edit and "ok" - widget will start working

To Reproduce - Zabbix CPU utilization

1. Add zabbix widget to board and add enpoint, leave host field blank(!) and choose metric CPU utilization
2. Edit endpoint - it is enough to just open it and save without applying changes
3. Open edit of your zabbix widget and provide wrong host and save (Invalid data)
4. Open it once again and provide proper host and save

Expected behavior

Data on widgets after steps provided above should be refreshed and widget should display it. (Currently "Invalid data" or just no data is still shown instead of proper content)

Notes

It would be great to check whether some other widgets and metric are not affected by this issue and apply fix on them if needed.
