updateShapeProperties complaining about missing fields property - google-slides-api

Question

Details
OS: Manjaro Linux
Node.js version: 10
npm version: 6
googleapis version: 51.0.0
Steps to reproduce
We are sending a google slide API request with updateShapeProperties:
"updateShapeProperties": {
"objectId": objectId,
"shapeProperties": {
"shapeBackgroundFill": {
"solidFill": {
"color": {
"rgbColor": {
"red": r,
"green": g,
"blue": b
}
},
"alpha": 1
}
},
"outline": {
"outlineFill": {
"solidFill": {
"color": {
"rgbColor": {
"red": 0,
"green": 0,
"blue": 0
}
},
"alpha": 0.1
}
},
},
"contentAlignment": "MIDDLE"
},
"fields": "*"
}
where objectId comes from one of any pageElement we get from slide.pageElements
We get a 400 response that states:
message: ""Invalid requests[2].updateShapeProperties: At least one field must be listed in 'fields'. (Use '*' to indicate all fields.)
This somehow used to work the past few months, and was wondering why it suddenly doesn't work right now. Did we have any changes or updates on the updateShapeProperties API?

Answer 1

I believe that [2] of Invalid requests[2].updateShapeProperties is the request body in your question. When I tested your request body, I could replicate your situation. The error message is At least one field must be listed in 'fields'. (Use '*' to indicate all fields.). When I tested "fields": "", I got the same error message. From this situation, I thought that it might be a bug.
When I searched this situation at the Google issue tracker, I found it. Ref
So as the current workaround, in order to avoid this error, in your request body, how about the following modification?
From:
"fields": "*"
To:
"fields": "shapeBackgroundFill,outline,contentAlignment"
