When the lost module receives such a response, then generate this message

http_client [functions.c:299]: curL_query_url(): Malformed URL used in http client (url: 
                                                                                         https://ls.example.com:9768/357yc6s64ceyoiuy5ax3o

lost [functions.c:325]: lost_held_function(): dereferencing location failed: 3

This error is fixed when if I strip spaces in a string of locationURI element.

Troubleshooting

Reproduction

Send xml eample from RFC as responce for lost_held_query function call.

Possible Solutions

Strip leading and trailing spaces of locationURI element.
