Hello,

My team has developed a workspace for data collection of publicly available GIS-data. The workspace uses HTTP-callers to download the data from different URL:s, and then the data is clipped from a predefined area of interest. The schemas and the features area separated and the rejoined later in the workspace. The output is written to an ESRI Geodatabase. 

Everything is working fine using FME Flow 2023.2.2.0 - Build 23781, but when I tried upgrading to FME 2025, I get an error:

“Esri Geodatabase Writer: Feature Type Definition 'd_y_n' was requested, but not defined. Please visit https://www.safe.com/support”

Does anyone have any insights into this issue?

Thanks in advance /Ville

    Deja vu. Not sure if this is the same issue but worth trying:

    Thanks for the reply ​@nielsgerrits. I tried an Attribute exposer, but I didn’t have any attribute named “fme_template_feature_type”. Could you send me a screenshot of how you did it? 

    Kind regards

    I tried to reproduce this in 2025.2.1 but I could not, it is probably fixed in this version. When I wrote the linked topic I had 2025.1.2 installed. What is your installed version?

    Hi, 

    Past experiences taught me that I need to check dynamic writing settings in every tool eacht time we did software upgrade. You can try the following:

    • Download the workspace from FME Flow and open it in Workbench. Check if the settings are still correct. It is possilble it defaulted to a unwanted setting. Fix it and reupload.
    • How are you combining the schema with the data? Is it from a fixed data source or are you combining it, or are you setting it via the SchemaScanner? Dynamic writing needs the schema source before you write the data. Otherwise Workbench is going to complain.
