What causes SkipInvalidFileNameNotSupportedForSource?

Skip invalid filename not supported for this source. Integration runtime configuration is incorrect or outdated. Authentication credentials or permissions are insufficient. The feature or setting is not supported for the selected connector or copy mode

How do I fix SkipInvalidFileNameNotSupportedForSource?

Open the copy activity Settings tab and disable the 'Skip invalid file names' fault tolerance option — the source connector does not support this setting.. Check the ADF documentation for the source connector to see which fault tolerance options are available for it — non-file connectors (SAP, SQL, REST) do not support file-level fault tolerance.. If using a file-based source connector (Blob Storage, ADLS Gen2), this setting requires the datasets to use Binary format — check whether format conversion is configured and remove it if binary copy is acceptable.. Rename invalid-named source files upstream so they do not need to be skipped — invalid file names (containing characters not permitted by the destination) cause deterministic failures.. Validate the pipeline after removing the incompatible setting.

Power BI Refresh Error:
SkipInvalidFileNameNotSupportedForSource

What does this error mean?

The source connector does not support the fault tolerance option to skip files with invalid names. Remove this setting or use a supported source connector.

Frequently asked questions

Does this configuration error affect every pipeline run?

Yes — configuration errors are deterministic. Every run fails until fixed; retrying does not help.

How do I validate an ADF pipeline configuration before running it?

Click 'Validate' in the ADF authoring UI for configuration checks. For data flows, use Debug mode with a small sample to validate expressions and mappings.

Can dynamic content expressions in ADF cause configuration errors at runtime?

Yes — @activity(), @pipeline(), or @dataset() parameters that resolve to null or an unexpected type cause runtime failures even when design-time validation passes.

Do configuration errors appear in the ADF activity output?

Yes — the ADF Monitor activity detail shows the error code and the specific property that is invalid or missing.
