Hi, I am creating pre‑signed PUT URLs in my app and getting **403 Forbidden** errors. When creating URLs via the Tigris dashboard they look like: ``` https://files.allaboutholes.vip/import-jobs.csv?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=...&X-Amz-Date=20251107T020219Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=... ``` When creating URLs via the application code below I get this shape: ```javascript const endpoint = 'https://fly.storage.tigris.dev'; const bucketName = 'holehub-dev'; const forcePathStyle = false; const deleteAfter = new Date(Date.now() + 1000 * 60 * 60); const s3Client = new S3Client({ region: 'auto', endpoint, credentials: { accessKeyId, secretAccessKey }, forcePathStyle, }); const signedUrl = await getSignedUrl( s3Client, new PutObjectCommand({ Bucket: bucketName, Key: '/jobs/imports/uploads/01K9E0WRQT8P0DM5GX65NZWXB2.csv', Expires: deleteAfter, ContentLength: fileSize, }), { expiresIn: 3600 }, ); ``` Resulting URL: ``` https://holehub-dev.fly.storage.tigris.dev/jobs/imports/uploads/01K9E0WRQT8P0DM5GX65NZWXB2.csv?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=...&X-Amz-Date=20251107T020358Z&X-Amz-Expires=3600&X-Amz-Signature=...&X-Amz-SignedHeaders=host&x-id=PutObject ``` The dashboard‑generated URL works, but the S3 client‑generated one returns: ``` HTTP/1.1 403 Forbidden Content-Length: 433 Content-Type: application/xml ... SignatureDoesNotMatch The request signature we calculated does not match the signature you provided. Check your key and signing method. /jobs/imports/uploads/01K9E0WRQT8P0DM5GX65NZWXB2.csv 1762481194277975954 ``` What could be wrong? I’m familiar with presigned URLs but new to Tigris.
