When updating a custom field via API, only 250 characters are accepted.

Issue Summary

The PUT API for align Epic is failing if the custom field value is greater than 250 characters. Epic's "Justification" custom field by API is limited to only 250 characters. This is however not seen for any other field for example, description. There is also no character limit if we update the Justification (customfield_70001) field from the UI, with the same value as the API example

Steps to Reproduce

1. Run the following API call with the value for customfield_70001 which is more than 250 characters.

   curl -X PUT "https://<JA URL>/rest/align/api/2/Epics/<epic id>" -H "accept: */*" -H "Authorization: Bearer <token>" -H "Content-Type: application/json;odata.metadata=minimal;odata.streaming=true" -d "{ \"id\": 2463, \"title\": \"<title>\", \"themeId\": <theme id>, \"description\": \"<description>\", \"primaryProgramId\": <program id>, \"state\": 1, \"type\": 1, \"additionalProgramIds\": [<program ids>], \"customFields\": [ { \"customfield_70001\": [ { \"value\": \"<value more than 250 characters>"} ] }, { \"customfield_70002\": null }, { \"customfield_70003\": null }, { \"customfield_70004\": null }, { \"customfield_70005\": null } ],}"
   

1. Check the output for the call

Expected Results

The API should be consistent with the UI.

Actual Results

We get a 400 error

[
  "value must be between 1 and 250 characters."
]

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
