Reporting a bug we’re seeing. We have a Content Type with a required Entry title field that has to match the following pattern:
^([a-z]+[a-zA-Z0-9]+)+((.([a-z]+[a-zA-Z0-9]+)+)?)+$
Essentially, it only allows text that is camelCased with dot separators. If we edit the field to be invalid, like with a trailing period, Contentuful becomes unresponsive. And if we try to access that entry again after that, Contentful also becomes unresponsive and we’re unable to open the entry.
Our work-around when we face this issue is to remove / relax the validation for the Content Type, then edit the entry in question to make it valid, and then re-enable the validation, but this is far from ideal. Hoping to get this bug on Contentful’s roadmap.
