Hello,

We are currently investigating this issue. To help investigate would you be able to provide a session ID when this issue occurs in the mobile player. Also do you happen to know the size of the image being uploaded.

Thanks,

I have also been suffering this issue for the last few days.
Again..
How are we meant to use these apps in a live environment when it’s so so buggy.
Jeez I reported about Patch not working on collections where initilally its a null value nearly a year ago and it’s still not fixed

Found couple bits:

Problem:

When you 'Ask In Powerapps' for the base64 representation of a camera image it also includes the 'data:image/png;base64,' part before the base64 data

Solution: Add a Label, Set is Text Property to a substitute function of the base64 data and replace 'data:image/png;base64,' with '' , then use this for your 'ask in powerapps'.

Problem:

Doesnt like blank data (nullvalue)

Solution:

Just do a simple If Isblank formula and replace with minimal image such as 'iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mNkYAAAAAYAAjCB0C8AAAAASUVORK5CYII='

Hi, Can we get an update on this?

Hi @gautmish, I am looking at the session ID you provided, but I am failing to find the "Construction of a PABinary should always result in a valid instance" error. Are you sure that you hit this error in the session you provided?

Regarding the error, there is currently a known regression in the area of uploading photos to SharePoint through binary data (using a custom connector and a Flow). One way to know if you are affected by this issue is the following:

1. Uploading a photo to SharePoint works on WebPlayer but not iOS or Android.
2. If you take a photo that results in a smaller image size, the upload will succeed. You can test this by taking a photo of a solid, white background.

We are currently working on a permanent fix.

Thanks,

Allen

Hi @Delid4ve,

We are using add picture control in our app . So we are getting blob storage URL , In powerapps i dont think it is possible to convert the same to base 64 URL (If possible to please lte me know). And for photo taken from camera , its not sending any triggering the flow , its failing before that .

Thanks

Hi @AllenKim,

Could you please let me know how soon this can be fixed .

you can get the binary data from that blob url using sql.

so:

add action, sql, add rows, set up a dummy table and save the data. (this automatically grabs the binary data from the bloburl)

now add a compose action, and use a function binarytobase64 (this converts the binary data to base64)

now do whatever you want with it, note: you will have to add the data:image/png;base64 to the front of the string if you want to put this in html code for instance
