If you feel the description in English is not clear, then you can append description in Chinese(just for Mandarin(CN)), thx! **
**Describe the bug**
A clear and concise description of what the bug is.
**To Reproduce**
Steps to reproduce the behavior, for example:
1. Start an initial DB and ZK, run `CreateDolphinScheduler` to import sql data
2. Start UI and API, DO NOT start master and worker
3. Click 'Create process'
4. Drag a task icon to dag editor
5. See error
**Expected behavior**
Exception can be captured and friendly information can be prompted in UI.
**Screenshots**
If applicable, add screenshots to help explain your problem.

If you feel the description in English is not clear, then you can append description in Chinese(just for Mandarin(CN)), thx! **
**Describe the bug**
A clear and concise description of what the bug is.
**To Reproduce**
Steps to reproduce the behavior, for example:
1. Start an initial DB and ZK, run `CreateDolphinScheduler` to import sql data
2. Start UI and API, DO NOT start master and worker
3. Click 'Create process'
4. Drag a task icon to dag editor
5. See error
**Expected behavior**
Exception can be captured and friendly information can be prompted in UI.
**Screenshots**
If applicable, add screenshots to help explain your problem.

If you feel the description in English is not clear, then you can append description in Chinese(just for Mandarin(CN)), thx! **
**Describe the bug**
A clear and concise description of what the bug is.
**To Reproduce**
Steps to reproduce the behavior, for example:
1. Start an initial DB and ZK, run `CreateDolphinScheduler` to import sql data
2. Start UI and API, DO NOT start master and worker
3. Click 'Create process'
4. Drag a task icon to dag editor
5. See error
**Expected behavior**
Exception can be captured and friendly information can be prompted in UI.
**Screenshots**
If applicable, add screenshots to help explain your problem.
