Customizing default sharepoint form in powerapps doesn't save after publishing to sharepoint

Previously I was using a sharepoint default form to send a request to my client. I was always able to fill all the fields in default form(fields being appointment type, reason, requested date, due date) and send it to client approval by workflow that was operating after 'Save' and it was working. However when I tried to customize my form using powerapps by adding one dynamic textfield that calculates the difference in the due and requested dates excluding holidays and weekends, my form doesn't save in sharepoint and I get a message like 'There was a problem saving your changes. The data source may be invalid.'


When I checked out the data source, it was all good. Each field especially required fields of my form has been given correct values. I don't understand where I am going wrong.


Is there any way of debugging this? How can I check out the json after the form submits and throws error? Or is my approach wrong?

Re: Customizing default sharepoint form in powerapps doesn't save after publishing to sharepoint

Hi @stiwari,


It is true that we do not have such debugging tool in Power Apps so far. I have found the idea below, you could vote there:


Additionally, you could also take use of some other tools to help troubleshooting:

F12 developing tools (if used PowerApps studio web version),

Or Fiddler web debugger tool.


You may also share the errors and formula that used, so that we could make some tests for further investigation.



Hope this can be helpful.


Best Regards,
