The entered text is too long. It exceeds the allowed limit of 32,767 characters.
The Table Grid Editor is using textarea to store data in edit mode. We're using Atlassian textarea custom field settings.
So we cannot put the string value longer than is set by default in the JIRA settings (32,767 characters).
- Navigate to the Administration - Advanced Settings in your JIRA.
- Change the value of jira.text.field.character.limit property to 0.
- Update the configuration.
