# Introduction
Encountered in issue in production where we have a lot of records that
has RICH_TEXT_FIELD set to `{}`
```sh
[Nest] 20106 - 02/19/2025, 12:43:08 PM LOG [MigrateRichTextFieldCommand] Generating markdown for 1 records
[Nest] 20106 - 02/19/2025, 12:43:09 PM LOG [MigrateRichTextFieldCommand] Error in workspace 3b8e6458-5fc1-4e63-8563-008ccddaa6db: TypeError: o is not iterable
```
## Fix
While reading `fieldValue` definition also strictly check if it's `{}` +
checking after JSON parse if it's an iterable to pass to the
`serverBlockNoteEditor` in order to be 100 bullet proof for prod
migration command
## Refactor Dry run
Implemented dry run
## Refactor to Idempotency
Made the script idempotent in order to avoid issues with re-running
commands
## Error repro
- In local checkout on v0.41.5 run `yarn && npx nx reset && npx nx
start`
- Create record manually in db that has a RICH_TEXT body to `{}`
- Checkout to main, `yarn && npx nx reset && npx nx build twenty-server
&& yarn command:prod upgrade-0.42:migrate-rich-text-field -d`
