Troubleshooting and Solutions

Correct Answer: B

If a folder you are copying consists of the files with different schemas, like different delimiters, quote char settings, variable number of columns, or some data issue, the Data Factory pipeline may return the following error:

Option A is incorrect.

When you reach the capacity limit of the integration runtime, you might be running a huge amount of data flow through the same integration runtime at the same time that makes the pipeline run get fail.

Option B is correct.

"DelimitedTextMoreColumnsThanDefined" error is generally returned when the folder you are copying has the files with different schemas.

Option C is incorrect.

Browser cache issue might result in a situation where you cancel a pipeline run, but pipeline monitoring often still demonstrates the progress status.

Option D is incorrect.

The option does not state the right cause for the given issue.

Reference:

The "DelimitedTextMoreColumnsThanDefined" error typically occurs when you are copying data from a delimited text file, and the number of columns in the data exceeds the number of columns specified in the schema definition.

Out of the given options, option B, "The folder you are copying has files with different schemas" is the most likely cause of this error. This error can occur when the schema definition of the data source and the schema definition of the data destination do not match. For example, if you are copying data from a folder that contains multiple delimited text files with different column counts, you may encounter this error.

Option A, "You have reached the capacity limit of integration runtime" is an unrelated error that may occur when you have exceeded the capacity limit of the integration runtime. This error typically occurs when you are performing large-scale data transfers, and the integration runtime does not have enough resources to complete the transfer.

Option C, "Browser cache issue" is not a likely cause of this error, as it is related to browser caching and not data copying.

Option D, "You have invoked REST API in a Web activity" is also an unrelated error. It can occur when you are using a Web activity to invoke a REST API, and there is an issue with the API endpoint or authentication.
