`to_json` times out

[ottz0]

Just upgraded to v5 and it appears that the json that was valid, now appears no to be valid or is timing out my browser.

How to reproduce

{{ servers | to_json | entities }} now does not render due to upgrade

Needs further investigation. tried parsing another object and that worked. Upgrade does not like the JSON output which worked fine before upgrading....SyntaxError: Unexpected end of JSON input

[ottz0]

I've dumped a collection it had references to other members in the collection such as next, previous, children and parent. Is the json trying to warp those references and getting into a loop and making it timeout?

{{ servers | to_json | entities }}`

What is the servers field? Can you share the field config from the blueprint's YAML file?

Also, are you able to share the data for the servers field that's causing it to error? (you can find that in the entry's markdown file).

[ottz0]

It's not in a Yaml file, I'm looping through a nav:collection.

This works

{{ servers = {{ nav:collection:marketplace from="/marketplace/{segment_2}" }} }}
{{ servers }}
    {{ title }}
{{ /servers }}

This also works

{{ nav:collection:marketplace from="/marketplace/{segment_2}" }}
    <div class="column is-6-tablet is-4-desktop">
        {{ title }}
    </div> 
{{ /nav:collection:marketplace }}

This works with the modifier

{{ nav:collection:marketplace from="/marketplace/{segment_2}" }}
    <div class="column is-6-tablet is-4-desktop">
        {{ title | to_json | entities }}
    </div> 
{{ /nav:collection:marketplace }}

This used to work but now now has errors: Maximum execution time of 30 seconds exceeded. SyntaxError: Unexpected end of JSON input.

 {{ servers = {{ nav:collection:marketplace from="/marketplace/{segment_2}" }} }}
 {{ servers | to_json | entities }}

Thanks! Can you share the blueprint for the marketplace collection?

Perhaps you have a circular reference through the related entries?

I.e. page 1 points to page 2, page 2 points to page 1 (or maybe 1 > 2 > 3 > 1). That would end up with an infinite loop when trying to serialize it to json (hence timing out).

I thinks that's whats happening. It's weird that this was working right before I went to upgrade to V5

[duncanmcclean]

Let's try and rule out it being an infinite loop / circular reference loop...

Can you try commenting out the various Entries fields from the blueprint, and see if that fixes the issue? If it does, can you try uncommenting the fields one-by-one to see which one is causing it.
