Describe the bug

1. I enter into the detail of a meeting, without being logged in as a User for example in "https://meta.decidim.org/assemblies/eix-lab/f/130/meetings/1159"

2. In the top bar, click "Enter"

3. I login with my user.

4. I'm redirected to the page with the meeting map. ("Https://meta.decidim.org/static_map?sgid=BAh7CEkiCGdpZAY6BkVUSSI2Z2lkOi8vbWV0YWRlY2lkaW0vRGVjaWRpbTo6TWVldGluZ3M6Ok1lZXRpbmcvMTE1OQY7AFRJIgxwdXJwb3NlBjsAVEkiDGRlZmF1bHQGOwBUSSIPZXhwaXJlc19hdAY7AFRJIh0yMDE5LTAxLTEwVDE2OjIzOjM0Ljc3MFoGOwBU--1c11923c715a4a0a60091bec9cb744bdd95b933f")

I understand that I should not make this redirect, if not I should return to the meeting.

I found the error at 0.15 in the metadata
