the class PayeeACHAccountExtractServiceImpl method getResolvedEmailBody.

/**
 * Helper method for replacing "[propertyName]"-style placeholders in the email body
 * with actual property values from the given Payee ACH Account, in addition to
 * replacing literal "\n" with newline characters accordingly. Potentially sensitive
 * placeholders will be replaced with empty text except for the bank name.
 * Placeholders referencing properties with value finders will print the matching key/value
 * label instead. Any placeholders that could not be resolved successfully will be replaced
 * with empty text.
