When we use the content in a single line it is working, But when we use in his kind of block, it is not working. Help needed.

Show us your blocks cause you most probably you are doing something wrong. I use join text to create marker json with no problem

Please find the attached files

I found the Mistake. In the Location name i used a Space. I replace the space with “-” and the problem is solved.

Thank you so much

Can you help me? I did the same thing as you did with error 12014 when showing the markers on the map.

Please debug your blocks with Do it and show me the values in global_json . Most probably in title or snippet you have empty spaces. For example if title is My home you will receive error 12014 but if title is My_Home then no error

I managed to solve the problem, really my title had spaces, but in order to use spaces I just put “” in the title and subtitle in json, leaving it like this image

Is firebase configured correctly ? url, token , bucket ?
