500 error from api when uploading a tag with value ending with "%" (percent) #4166

Author: Matt It seems that this might be due to a lack of Content-Type header on the request. When this isn't present, Rails seems to assume it's application/x-www-form-urlencoded, which is a reasonable default for web middleware and RFC compliant. However, this means it would attempt to interpret the '%' as an escape code and fail whenever it's not followed by two hex digits. It appears to work as expected when the Content-Type is set to "text/xml" in my tests. It's possible this isn't the same issue as you're seeing. If this is the case, and a Content-Type header is being sent, please could you provide a tcpdump of the failing session for further analysis? |

Author: Koying I confirm setting the Content-Type to text/xml solves the problem. Sorry for the noise. |

Author: fkv This should cause a 4xx error, not a 500. An internal server error is always a serious bug, no matter whether the request was valid or not. This issue affects a lot of users, because I get it with Markaartor (latest stable version), which is one of the major Openstreetmap editors. There may be a bug in Merkaartor too, but anyway the internal server error is a server bug. |

Author: mmd I'm getting a HTTP 400 when using Content-Type application/x-www-form-urlencoded When using application/xml, everything works ok. Closing here, as the reported HTTP 500 no longer occurs. |

The api returns a 500 error when trying to upload a diff change with a tag value ending with a percent.
A tag value with a percent in the middle works fine.
Example osmchange:[[BR]]
The text was updated successfully, but these errors were encountered:
