Hi All We are using a script to programmatically delete unus

Question

Hi All We are using a script to programmatically delete unused blocks from our dev environment via the API using `prefect block delete ` However when trying to delete these blocks we keep getting 409 Conflict error codes on those blocks Strange because the same blocks can be deleted just fine through the UI Any ideas on how we could resolve this Feeling like some kind of issue with how the API is handling block deletion

Nate · Answer

hi < Ananya Mishra> can you share the script that you re using and the output of `prefect version` if possible

Ananya Mishra · Answer

it s a bit layered but the gist is we collect all the block slugs to delete into an python dict like this ` kubernetes job deployment infra 16899 s3 deployment storage 16451 kubernetes job deployment infra 16541 ` and then run `subprocess run f prefect block delete slug shell=True ` in python for each block

is there a reason you re using the CLI I would <https github com PrefectHQ prefect blob main src prefect client orchestration py L1116|use the client for this>

Ananya Mishra · Answer

cool let me try that

Nate · Answer

cool lmk if you need any more direction on that you should just have to collect the block ids you need and pass them to that client method

Ananya Mishra · Answer

is id different from the slug i posted above

Nate · Answer

so I would use <https github com PrefectHQ prefect blob main src prefect client orchestration py LL1260C30 L1260C30|this> to read the block document by `slug` as you have above grab the ID a UUID off each one with `block document id` and then pass that value into `delete block document`

Nate · Answer

```from prefect import get client from uuid import UUID slugs = block type block doc slug async with get client as client for slug in slugs type slug name slug = slug split block document = await client read block document by slug name slug type slug await client delete block document UUID block document id ``` should be something like this

Ananya Mishra · Answer

hmm yeah that didn t really change anything still getting ```httpx HTTPStatusError Client error 409 Conflict for url <https api prefect cloud api accounts b8194971 9f89 43fe a099 69552528a88a workspaces e0b524be 50ed 4eca b77b d2a1b2ade39f block documents 5fd2e02b 160e 4cf4 a990 5754e5e6230a> ```

Ananya Mishra · Answer

i think we need to take a closer look at what is happening with those objects on the server side that could be leading to these 409s

Ananya Mishra · Answer

is there some other process we don t see using them

Ananya Mishra · Answer

perhaps you can take a look at that exact object i sent and see what s up there or if you can delete it programmatically from your end

Nate · Answer

ah are any of these blocks used by any of your deployments that exist

Nate · Answer

i noticed your slugs were referring to storage and infra blocks so if these were associated with an active deployment this would be expected behavior although we could probably improve the error message

Ananya Mishra · Answer

i see so then we need to make sure all associated deployments are deleted first

Nate · Answer

yes

Ananya Mishra · Answer

also i guess it s good for yall to note this is permitted by your UI while the API seems to catch it

Nate · Answer

hmm i will check on that
