ErrorMessage: Failed to publish web layer

[wilcow]

Attempting to publish Enterprise GIS layers to AGO and after an hour or so, I receive this message:

Server Response: {"error":{"code":400,"message":"Invalid URL","details":["Invalid URL"]}}

I've seen this error when trying to publish features with Definition Queries, but none of these layers have DQs. 

A couple of them do have related tables, but I removed those on the latest attempt to no avail. 

There are a ton of features in the project I'm publishing - could this be a simple time-out issue?

[Robert_LeClair]

Are you publishing all the layers out at once and receive this message?  You could test each layers success (or failure) of publishing as a web layer by selecting each one individually, right-clicking on the selected layer->Sharing->Share as web layer to see which one errors out.

[wilcow]

Yessir I was publishing all at once. I tried to publish them one by one as you suggested and got the same error on the first FC I tried.

to be sure, I opened a new project and tried the same FC by itself - same result, so it seems that there's a problem with that FC.

[Robert_LeClair]

Depending if that one FC has any behaviors on it (i.e. subtype, domain, etc.), you could export it out as a shapefile and reimport it as a geodatabase feature class to see if that "fixes" it.  Then reshare to a web layer.  What is the result - error or success?

[wilcow]

I tested that process (export to .SHP and reimport to GDB and then publish) and it worked for that FC.

Now I'll add it back into the project and see if it still errors out.

More on this: found several other FC's in the map and discovered I can ID which ones will work by looking at their attribute tables in ArcGIS Pro

for the FCs that fail on publishing, the attribute table appears to be blank (no rows or headers and no active tools)

I'll upload a screen shot

edit: these same FCs work as expected in ArcMap (v10.6) - I can see the attribute table, anyway

[Robert_LeClair]

Question - do any of your FC tables have a date field and if so, do you see a value of 12/30/1899?  Weird I know but I'm researching some BUGs that talk about this.

[wilcow]

as a matter of fact they do. Yes to both.

I seem to recall this being an issue when I created these features - had to add and calculate new date fields for several datasets, I think

[Robert_LeClair]

Okay - test this.  Create a copy of the FC in your geodatabase.  Delete the date fields, try to publish as a web layer.  Success or not so much?

[wilcow]

Done. Out of 4 Date fields I found 2 that contained "12/30/1899". 

I removed those fields and was able to publish the Feature Layer to AGO.

I'm going to test whether changing that value might have an effect on one of the other FCs
