Strapi Upload S3 + Localstack

I think the problem is that Strapi (specifically strapi-provider-upload-aws-s3) doesn’t support path-style addressing, this is http://localhost:4566/, that is the way to connect the local s3 service from the host.

You can add forcePathStyle: env('AWS_S3_PATH_STYLE', false), as given below into your middlewares.ts and then you would add a env variable for local development with AWS_S3_PATH_STYLE=true. Note that this .ts references a newer version of strapi, but it might be also applicable without s3Options: { to your case.

I’m not sure about the exact reason, but I think that those options are then also applied for the s3 configuration.

     providerOptions: {
        s3Options: {
          [...]
          forcePathStyle: env('AWS_S3_PATH_STYLE', false),
          [...]

By applying this configuration your path-style addressing should work.
