Debugging: "status": 400, ...



I have a Flow that intermittently fails (4-5 instances over the past 3 months) at "Update File Properties" with a "Bad Request" heading.


  • Here is a snapshot of the steps:


Here is the Status 400 error message at the bottom of Update File Properties: 


  "status": 400,
  "message": "Invalid text value.\n\nA text field contains invalid data. Please check the value and try again.\r\nclientRequestId: 24d0ed01-1950-4c63-8d47-f6e2ae5026c6\r\nserviceRequestId: bc268e9e-c008-7000-51f9-7f06ae770f58"

Unfortunately, I don't know which Text Field has contains the invalid data! 

  • The fields are not clearly listed in the error message
  • Nor is there an indicator on any of the fields that it contains invalid data


How do I debug the issue here? 


Thank you

Hi @ericonline,


Could you share the detailed screenshot of your flow configuration? What properties are you going to update?


I made a simple test with the similar configuration. However, it ran succeed.



Could you share more details to help reproduce it on my side?


Best regards,

Hello @v-yamao-msft


Below is a detailed screenshot of the Flow. The properties I'm updating are items in a Word template. The Flow runs all the time without issue. It only fails intermittently. 


Ideally, I'd like to know HOW to debug this error. 


Thank you



Hi @ericonline,


What are the column types you are going to update?


Do you have a Multiple lines of text column? If the character length exceeds the limit, the flow will return the error message.

Thank you for the response @v-yamao-msft. Is there anyway to determine WHICH field has the issue? As you can see there are 30-40 fields. Would love to have the error point me diretly to the field in question. 

Not applicable




I have a similar problem, could you help us to know which column have the error and the limit of caracter for a individual column? . @ v-yamao-msft.




I agree - I have a document with 65 fields being updated. Just being told one of them has a problem without being able to debug which one it is is frustrating...  Suspect it may be do to with column length  as others have suggested but I am going to have to go through all 65 to check!!  woudl be useful if the error message could identify which field has the problem 🙂
