Message
The following string field values were truncated because they contain values that exceed the maximum length: <fields>
Description
The string values being written exceed the maximum length for the fields specified in the message. The values will be truncated to the maximum length supported by the field.
Solution
When creating feature layers or tables using Data Pipelines, the maximum supported string field length is 5000 characters.
Feature layers and tables created outside of Data Pipelines may contain string fields with other character limits. To verify the maximum field length set for a field, go to the Data tab of the feature layer or table item page, switch to the Fields view, and inspect the length value for the field of interest.
