Images/Videos in storage appearing broken after upgrading to 1.9.6

I am running into a storage issue after upgrading my self-hosted Appwrite instance , all of my previously uploaded images and videos are now showing as broken icons in the Appwrite console and failing to render in Flutter app

hmm that's strange,

can you tell me :

• if your not using S3 ? if you are using S3, are you sure the configuration is correct ?
• if is there error logs in the appwrite container ? (if yes could you share thoses logs ?)
• are the files in the volumes ?

no im not using s3

here appwrite logs

seems to be a 400 error, so maybe your request is bad.

could you share the preview request your making (if possible both from the SDK/Code and the Network request from the devtools or add a debug logs with the url, headers and maybe body if present if your using a mobile app)

like if i understand the error correctly you seems to not pass width/height (or pass them as empty value) which then fails to display

and regarding the files ? are they present in the volume ?

Yes the files exist on disk in the storage volume

okay im sending it..

oh, it's not the same request ... and this one is 200, not 400

also i'm wondering, do you use compression ?

this is directly from appwrite console

ok so the fact that preview is throwing 400 and view is showing 200 tells me there is something bad happening either with the Compression and/or the Encryption.

did you change anything after the upgrade ? is the encryption key still passed (does the env from the old an ew version are the same for _APP_OPENSSL_KEY_V1)

Nope, only the default appwrite configuration

No, i just follow the upgrade wizard, no change

tho i really think it's the Encryption key that somehow changed, because of the warn from the GZIP, where is think it try to decompress the image, but it's "data error" so i think it's already broken there.

then very strange, by any chance, do you still have a backup of the older .env and compose before the upgrade ? so we could compare

yes i do have both

could you check if both have the OPENSSL key and if they are the same ?

okay let me see

just to be sure, the Jul 2 is also the same ? (since the two your showing are from Aug 4, today)

also remove them from here, as they are encryption key

wait i see something the new have more back slash no ?
