trying to grab data from an external system and use it to update Contact records in Salesforce. 99% of the time this works great, but I've recently seen the following error that is a bit puzzling since the First Name I'm attempting to write in is only 20 characters long:
Contact.FirstName = externalUserData.firstName
Ciphertext of length 127 bytes can't be written into a column of length 120 bytes for the "Contact.FirstName" field for Entity Id...
Is this unrelated to the length of the field? Some searching brought up Shield encryption but I can't find this error or documentation on that so any help would be much appreciated!
