bolt-python: Error in chat_postMessage method

I tried the following code:

block = [{"type": "section","text": {"type": "mrkdwn","text": "Erro na consulta " + str(datetime.now())}}]
client_bot.chat_postMessage(channel=channel_id, blocks = block)

And i got the answer:

Failed to run listener function (error: The request to the Slack API failed. (url: https://www.slack.com/api/chat.postMessage)
The server responded with: {'ok': False, 'error': 'invalid_blocks', 'errors': ['invalid_url [json-pointer:/blocks/0/slack_file.url]'], 'response_metadata': {'messages': ['[ERROR] invalid_url [json-pointer:/blocks/0/slack_file.url]']}})

This same code ran successfully about four hours earlier, but now it has this error.

Can anyone help me?

Glad you got it fixed!

FYI, we actually will be rolling back the new slack_file property / feature of image blocks today due to various issues it caused for customers (including the problem you experienced earlier). So please continue using the image_url property as I see you are doing in your last screenshot for the time being.

I will close this issue now but if you have further issues here, feel free to re-open or file a new issue.

@filmaj i solved!! 😃

I just use the same token at the following parts:

Starting bot at the beggining of code:

Upload file (image) in slack cloud.

And for send file, i used the method below:

Sure! I appreciate contribute into this task!

But i dont fix error yet. Now, i tried like this:

client = WebClient(token=SLACK_USER_OAUTH_TOKEN)

result = client.files_upload(channel=channel_id,file=path, initial_comment = 'Rentabilidades')
result_url = client.files_sharedPublicURL(file = result['file']['id'])

website = result_url['file']['permalink']
print(website)

And the block used was:


say(

            blocks = [
                
                {
                    "type": "section",
                    "text": {
                        "type": "plain_text",
                        "text": 'Última atualização: '+str(infos[1])+' '+str(infos[2]) + ' | ITD do IPCA é o mesmo do FOCUS FIC FIA (2020-12-28)\n'
                    },
                    "accessory": {
                        "type": "image",
                        "slack_file": {
                            "url": infos[0]
                        },
                        "alt_text": "Rentabilidades"
                    }
                }

                
            ]
        )

I got the same error:

Sure!

The block is below:


say(

            blocks = [
                
                {
                    "type": "section",
                    "text": {
                        "type": "plain_text",
                        "text": 'Última atualização: '+str(infos[1])+' '+str(infos[2]) + ' | ITD do IPCA é o mesmo do FOCUS FIC FIA (2020-12-28)'
                    },
                    "accessory": {
                        "type": "image",
                        "slack_file": {
                            "url": infos[0]
                        },
                        "alt_text": "Rentabilidades"
                    }
                }
            ]
        )
