NoMethodError downcase s3_bucket_name absolute_base_url

Support Self-hosting

AI-generated summary

The discussion revolves around resolving a NoMethodError exception, which occurs when trying to call the downcase method on a nil value in the s3_bucket_name method. kinqsley reported the error, and pfaffman suggested checking the S3 bucket configuration, recommending the use of environment variables as described in the Using Object Storage for Uploads (S3 & Clones) guide. kinqsley confirmed configuring S3 through the admin setting page but was unsure if environment variables were still required. pfaffman reaffirmed the need for environment variable configuration. However, codinghorror pointed out that the issue might be due to a blank S3 upload bucket field, causing the downcase method to be called on a nil value.

There is no s3_bucket_name in the setting page.

How have you configured your S3 buckets? You might have a look at Using Object Storage for Uploads (S3 & Clones) and configure S3 with environment variables as described there.

I have configured my s3 through the admin setting page.

Do I still have to configure the S3 environment variables in app.yml?

That’s what I recommended.

Isn’t this because you left the S3 upload bucket field blank? It looks to me like it is trying to call downcase on a blank value.
