[Help] Error in terminal when running tests

[Aroot42]

Hi, I can have Cenfun.

I ran into a problem when I run tests, and there is already data in the reports folder.

-When I run through Test Explorer, I see an error in the console and the tests hang indefinitely. Need to restart IDE.
-When I run using the script, I see an error in the console, and the script launch is interrupted.

I tried version 2.8.4 and above and completely reinstalled all node modules.

Is there anything you can recommend solving this problem?

My Report config

            'monocart-reporter',
            {
                name: 'My Test Report',
                outputFile: './MonocartReport/Report.html',

                columns: (defaultColumns: any[]) => {
                    defaultColumns.splice(3, 0, {
                        id: 'azure',
                        name: 'Azure link',

Could you please try latest version 2.9.8?
I can't figure out what the problem is base on the message and config you provided.
Guess that the problem is Monocart outputDir ./MonocartReport can not be removed.

• try disable trend option
• try use another directory: outputFile: './MonocartReport-new/Report.html'

Already use 2.9.8.
The trend option is definitely the problem!!

1. I tried to remove trend from the config and everything goes well
2. I tried to add an intermediate folder for the trend in the path "./MonocartReport/Trend/Report.json" and it also helped. But the file with the trend still appeared in the "MonocartReport" folder.

you forgot return in trend, try

trend: () => {
              return new Promise<void>((resolve) => {
                        
              }),
}

Or

trend: async () => {
              await new Promise<void>((resolve) => {
                        
              }),
}

add async/await construction

trend: async () =>
                    await new Promise<void>((resolve) => {
                        const fs = require('node:fs');
                        fs.readFile('./MonocartReport/Report.json', (error: any, data: string) => {
                            if (error) {
                                console.log(error);
                                resolve();
                                return;
                            }
                            const json = JSON.parse(data);
                            resolve(json);
                        });
                    }),

it not helped

[cenfun]

Never mind, I made a mistake, your way of trend is correct, let me think about it

[cenfun]

Could you please try monocart-reporter@2.9.9

Everything seems to be working fine. I'll check it out for a couple more days.
