Plus sign (“+”) in product name causes 404 error in prosEO Ingestor (character escaping) #255
Description
Description:
When downloading products through the prosEO Ingestor, a 404-199 error occurs if the product name contains a plus sign (+).
The issue appears to be caused by the fact that the + character in HTTP query parameters is interpreted as a space. As a result, the Ingestor searches for a product name containing a space and cannot find the correct file.
The missing URL encoding (escape) of the plus sign likely occurs in the PRIP API service, when it retrieves the download token from the Ingestor.
Steps to Reproduce
Attempt to download a product whose name includes a + character via the PRIP API.
Observe that the ProSEo Ingestor returns a 404-199 error.
Compare the requested filename and the actual filename in the S3 bucket — note the mismatch caused by the + being treated as a space.
Expected Behavior
The product should be successfully retrieved even if the filename includes a + character. The + should be properly URL-encoded (%2B) in all HTTP requests.
Suggested Fix
Ensure that the + character is correctly escaped/encoded in the PRIP API service when generating or passing download tokens to the Ingestor.
Additional Context
The issue was observed when comparing API responses with S3 bucket filenames.
Discussed and confirmed as likely a PRIP-API-side issue (see Thomas’ analysis).
