Describe the bug

I'm receiving an error when trying to transfer using the CLI. After generating my transfer token, I run the command yarn strapi transfer --to https://my-prod-strapi-app MY-TOKEN --force

I then receiving the following error

Starting transfer...
✔ entities: 21 transfered (size: 10 KB) (elapsed: 357 ms)
⠹ assets: 0 transfered (size: 0) (elapsed: 0 ms) node:events:505
      throw er; // Unhandled 'error' event
      ^

error Command failed with exit code 1.

Steps to reproduce the behavior

1. Go to Strapi admin
2. Click on Settings
3. Click on Transfer tokens
4. Click on generate token (give yourself full access)
5. Go to local application terminal
6. Type the command yarn strapi transfer --to https://my-prod-strapi-app MY-TOKEN --force

Expected behavior

I should not receive the error and my local data should transfer successfully to my remote application

[jwright04]

After digging into this for a few hours, I downgraded to 4.11.5 and was able to complete my transfer successfully. Definitely seems like an issue with version 4.12

It looks like you didn't pass the --to-token, can you confirm in your example the MYTOKEN you just cut that flag out or you weren't passing it?

Thanks for the report! Could you please let me know the following for both the local Strapi and the remote Strapi:

• Are you using local files or a file provider?
• Have you changed the admin url?

[guillermo-t3]

Same problem in 4.12.5 Token is provided, from s3 to s3. Default admin URL. From local to ec2 / rds (behind docker)

[bieblebrox]

Experiencing the same issue on 4.15.5

Transferring from remote (dev) instance running on Google Cloud Run to local works fine, but transferring from the local to another remote instance (staging) throws this error.

npx strapi transfer --to $STAGING_INSTANCE --to-token $STAGING_TRANSFER_TOKEN
? The transfer will delete existing data from the remote Strapi! Are you sure you want to proceed? Yes

Node.js v18.19.0

It seems to be an asset transfer issue. I can confirm the Media library is working fine on the staging instance

[chrisfernandes102]

Are there any updates on this? @bieblebrox I am running into the EXACT same issue here.

[alexbudin]

Same here for latest version of Strapi.
